Dear All,
Thanks in advance.
I found below deadlock in postgresql logs.
I cannot change calling of REINDEX and insert query sequence because it is execute automatically through some cron script.
Does this mean that you reindex quite often based on a schedule. Personally I don't prefer that. To me it is like you are trying to fix something that is not broken.
Ideally reindex only what needs to be reindexed. I would not want to reindex a table in OLTP env.
ERROR: deadlock detected
DETAIL: Process 2234 waits for AccessShareLock on relation 16459 of database 16385; blocked by process 4111.
Process 4111 waits for ShareLock on relation 16502 of database 16385; blocked by process 2234.
Process 2234: INSERT INTO table1 ( id , unique_id )VALUES( '1', '4')
Process 4111: REINDEX TABLE table1
Could you please provide any solution to resolve this deadlock.
Regards,
Yogesh
