From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 218+ messages in thread

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05 Erik Wienhold <ewie@ewie.name>

From: Erik Wienhold @ 2025-08-04 22:05 UTC (permalink / raw)

Move handling of default tablespace for CREATE OR REPLACE MATERIALIZED
VIEW from create_ctas_internal to ATPrepSetTableSpace.  It feels cleaner
that way in my opinion by not having to resolve the tablespace name just
to pass it to AlterTableInternal.  The default table space is passed as
empty string to AlterTableInternal.
