Delete my PostgreSQL Database
I can't delete my PostgreSQL Database, can you tell the steps to follow to do so?
When you try to delete your PostgreSQL database you may get an error:
postgres=# DROP DATABASE nuxeo; ERROR: database "nuxeo" is being accessed by other users
If you're sure there's no other user connected, then it may be because PostgreSQL has a pending prepared transaction that's never been committed or rolled back, which should never happen except if the database is shut down in an unclean manner (machine crash). To check for this:
SELECT database, gid FROM pg_prepared_xacts;
2.Depending on the number of results, follow one of the steps below.
- If you get a result, then for each transaction gid you must execute a
ROLLBACKfrom the database having the problem:
ROLLBACK PREPARED 'the_gid';
nuxeo=# SELECT database, gid FROM pg_prepared_xacts; database | gid ----------+----- nuxeo | 131075_MS03ZjAwMDEzYTo0YTg5MjA5NzoxMDczMg== (1 row) nuxeo=# ROLLBACK PREPARED '131075_MS03ZjAwMDEzYTo0YTg5MjA5NzoxMDczMg=='; ROLLBACK PREPARED
- If you have lots of transactions you can run this psql scripts:
\t \a \o /tmp/remove-transactions.sql SELECT 'ROLLBACK PREPARED ''' || gid || ''';' AS cmd FROM pg_prepared_xacts WHERE database=current_database(); \o \i /tmp/remove-transactions.sql
