Do you have a lot of especially long statements being tracked
in the pg_stat_statements view?* well, the view was showing the query
column null.*
* but looking on pgss_query_texts.stat there are very large sql
statements, of around ~ 400kb, multiple thousands. *
Are there any other signs of distress
in the postmaster log, like complaints about being unable to write
pgss_query_texts.stat? *no, just complaints for reading it. *
Thanks
