I have been having disk errors that have corrupted something in
my postgres database. Other databases work ok:
Running on Ubuntu 10.04.
paul@kitanglad:~$ psql -U postgres
psql (9.4.5)
Type "help" for help.
postgres=# SELECT pg_catalog.pg_is_in_recovery();
ERROR: could not read block 3 in file "base/12511/12270": read only 4096 of 8192 bytes
postgres=# \c pjtest
You are now connected to database "pjtest" as user "postgres".
pjtest=# SELECT pg_catalog.pg_is_in_recovery();
pg_is_in_recovery
-------------------
f
(1 row)
Since this is the "postgres" database, dropping and re-creating it
doesn't seem possible. pg_dump also gets the same error when I run
it on "postgres" so pg_basebackup will probably get the same error.
The only thing I can think of is to create a completely new data directory
with initdb and pg_dump/restore all the databases in the cluter to the
new data directory.
Is this my only option?
