Just additional information I'd like to tell.
I've got an additional error:
Relation blablabla already exists.
It's also connected with previous mail command about cretating temporary
table.
Greep'ing though src code I'v found almost on;y one place where sush kind of
error can happen:
src/backend/catalog/heap.c: 712
It's a
heap_create_with_catalog(const char *relname,
Oid relnamespace,
TupleDesc tupdesc,
char relkind,
bool shared_relation,
bool
allow_system_table_mods) ( ) function which is
/* --------------------------------
* heap_create_with_catalog
*
* creates a new cataloged relation. see comments above.
* --------------------------------
*/
as it is in src code.
May be it'll help someone to solve my problem.
