Any help or hint would be greatly appreciated.
Version 9.5.10
* PostgreSQL stopped, saying it needs vacuum.
* Checked the tables' age, and the top rows are as follows:
table_name | age | table_size
--------------------------------------------+------------+------------
pg_temp_31.tt_wms2_status | 2146483647 | 0 bytes
pg_temp_31.tt_wms2_string | 2134022566 | 0 bytes
pg_temp_16.tt_wms2_status | 1464468964 | 0 bytes
pg_temp_182.tt_wms2_status | 1461637687 | 0 bytes
pg_temp_182.tt_wms2_string | 1453357513 | 0 bytes
pg_temp_16.tt_wms2_string | 1452951861 | 0 bytes
pg_temp_4.tt_wms2_status | 1452494376 | 0 bytes
...
( i.e., all are temp tables. )
* PostgreSQL hint says, "Stop the postmaster and vacuum"
* Tried to vacuum in single-user mode, only in vain, with something like drop that table, and "You might also need to commit or roll back old prepared transactions." also says xid will wrap around after 999998 transactions.
* Tried to drop table pg_temp_31.tt_wms2_status, tried to drop schema pg_temp_31. Nope. PostgreSQL hint says, "Stop the postmaster and vacuum"
So apparently I'm in some loop without any clear way out.
Two questions:
(1) Can I revive this database?
(2) How did this possibly happen?
