Dear guys, we are using Postgresql 9.6.1 with Rubyrep in order to replicate some tables across two different, and remote, database servers. Since few weeks sometimes when inserting/updating some rows, the statement remains waiting and table seems locked for insert/updates.
When i issue "select * from pg_stat_activity" no query is locked. I only obtain this error messages when i kill (i also try directly from bash with pgsql) with "ctrl+c" the locked insert: ERROR: canceling statement due to user request CONTEXT: while updating tuple (0,7) in relation "TABLE" SQL statement "UPDATE TABLE SET FIELD=NOW() WHERE FIELD IS NULL" PL/pgSQL function TRIGGER_NAME() line 3 at SQL statement How can i see what is locking my table/tables? Thank you! F
