#5055 closed (fixed)

Postgres version mismatch

Reported by: donarb@… Owned by: adrian
Component: Database layer (models, ORM) Version: master
Severity: Keywords:
Cc: Triage Stage: Ready for checkin
Has patch: yes Needs documentation: no
Needs tests: no Patch needs improvement: no
Easy pickings: UI/UX:


The get_sql_flush() method in django/db/backends/postgresql/ uses "ALTER SEQUENCE". This method was added for the test system's fixture loading.

The get_sql_sequence_reset() method in core/ uses the older "SELECT setval()" method, available in PostgreSQL 7.3. "ALTER SEQUENCE" was added in PostgreSQL 7.4.

This patch changes both postgresql/ and postgresql_psycopg2/ to use the setval() method for resetting the sequence.

(In [6009]) Fixed #5055 -- Changed Postgres DatabaseOperations.sql_flush() to use 'SELECT setval()' instead of 'ALTER SEQUENCE', because the latter only works with Postgres 7.3+. Thanks, Don Arbow
