The new stats collection system doesn't need temporary directory, so
just remove it. pg_stat_statements modified to use pg_stat directory
to store its temporary files.  As the result basebackup copies the
pg_stat_statments' temporary file if exists.

* [PATCH v7 2/3] Handle default tablespace in AlterTableInternal
@ 2025-08-04 22:05  Erik Wienhold <ewie@ewie.name>
  0 siblings, 0 replies; 250+ 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>

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.

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; 250+ 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; 250+ 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>

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.

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; 250+ 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; 250+ 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>

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>

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; 250+ 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; 250+ 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

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.
