The following bug has been logged on the website:
Bug reference: 14844
Logged by: Hans Buschmann
Email address: buschmann@nidsa.net
PostgreSQL version: 10.0
Operating system: Windows x64
Description:
After pg_dump/pg_restore of individual databases from 9.6.5 to 10.0 I have
to set the search path for each database according to the schemas used (the
searchpath is not restored with pg_restore).
This is done with a cmd like
ALTER DATABASE cpsdb SET search_path TO public,part1,part2,part3;
In the application I do not handle the search_path, but need access to all
mentioned schemas.
For one database this alter database cmd succeeded, the application works.
For the second database I also entered the command, but the search_path is
not set in the application.
When trying to change or reset the search path the following error occurs
(PG 10.0):
didisdb=# ALTER DATABASE xxxdb SET search_path TO public,xxxo,xxxp;
ERROR: duplicate key value violates unique constraint
"pg_db_role_setting_databaseid_rol_index"
DETAIL: Key (setdatabase, setrole)=(19084, 0) already exists.
Even resetting the search_path with
alter database xxxb set search_path to "$user", public;
ERROR: duplicate key value violates unique constraint
"pg_db_role_setting_databaseid_rol_index"
DETAIL: Key (setdatabase, setrole)=(19084, 0) already exists.
produces the same error.
I never experienced duplicate key violations in postgres catalog
relations.
PS: setting the search_path with set in the psql session works, but is not
permanent...
What am I missing here?
