Hi Pavel,
I gave this a quick try-out with the script I had from previous
versions,
and found these two errors:
------------
drop schema if exists schema1 cascade;
create schema if not exists schema1;
drop variable if exists schema1.myvar1; --> error 49
create variable schema1.myvar1 as text ;
select schema1.myvar1;
let schema1.myvar1 = 'variable value ""';
select schema1.myvar1;
alter variable schema1.myvar1 rename to myvar2;
select schema1.myvar2;
create variable schema1.myvar1 as text ;
let schema1.myvar1 = 'variable value ""';
select schema1.myvar1;
alter variable schema1.myvar1 rename to myvar2; --> error 4287
select schema1.myvar2;
------------
The above, ran with psql -qXa gives the following output:
drop schema if exists schema1 cascade;
create schema if not exists schema1;
drop variable if exists schema1.myvar1; --> error 49
ERROR: unrecognized object type: 49
create variable schema1.myvar1 as text ;
select schema1.myvar1;
myvar1
--------
(1 row)
let schema1.myvar1 = 'variable value ""';
select schema1.myvar1;
myvar1
-------------------
variable value ""
(1 row)
alter variable schema1.myvar1 rename to myvar2;
select schema1.myvar2;
myvar2
-------------------
variable value ""
(1 row)
create variable schema1.myvar1 as text ;
let schema1.myvar1 = 'variable value ""';
select schema1.myvar1;
myvar1
-------------------
variable value ""
(1 row)
alter variable schema1.myvar1 rename to myvar2; --> error 4287
ERROR: unsupported object class 4287
select schema1.myvar2;
myvar2
-------------------
variable value ""
(1 row)
thanks,
