 Postgres prompts the above error, mostly because the Postgres database server has hardware problems, or crashes. Fixing it means that some data may be lost. If the error is an alarm or a monitoring table, the contents of these tables basically do not involve the user's business data. You can perform the following methods to repair the user:

For example, if the above figure indicates that there is a problem with the omm.tbl_fm_event_log table, you can follow the steps below to perform the repair.

Execute in the psql command line

# SET zerodamagedpages = on;

# VACUUM FULL omm.tbl_fm_event_log;

if you want recreate index :

REINDEX TABLE omm.tbl_fm_event_log;
