> Did try by encapsulating the create and drop queries within EXECUTE, but it seems to be giving the same error. The changed function is as follows:
You need to execute the insert-statement also:
test=# create or replace function tmp_table() returns int as $$begin
execute 'create temporary table tmp_foo(i int)'; insert into tmp_foo
values(1);drop table tmp_foo; return 1;end;$$language plpgsql;
CREATE FUNCTION
test=*#
test=*#
test=*# select * from tmp_table();
tmp_table
-----------
1
(1 row)
test=*# select * from tmp_table();
ERROR: relation with OID 187431854 does not exist
CONTEXT: SQL statement "insert into tmp_foo values(1)"
PL/pgSQL function "tmp_table" line 1 at SQL statement
test=!# rollback;
ROLLBACK
test=# create or replace function tmp_table() returns int as $$begin
execute 'create temporary table tmp_foo(i int)'; execute 'insert into
tmp_foo values(1)';drop table tmp_foo; return 1;end;$$language plpgsql;
CREATE FUNCTION
test=*# select * from tmp_table();
tmp_table
-----------
1
(1 row)
test=*# select * from tmp_table();
tmp_table
-----------
1
(1 row)
test=*# select * from tmp_table();
tmp_table
-----------
1
(1 row)
test=*#
Peculiar, the drop table works without execute...
