I know there are a lot of moving parts to this issue but I think I've eliminated most of them and the problem comes down to the postgresql server generating a statement_timeout error after 10 seconds when the connection statement_timeout is actually set to 15 minutes.
My web server gets a database handle which it keeps for the duration of the function that generates the response. Multiple queries can be sent and will use the same handle. After getting the handle I issue "show statement_timeout" and log the result which shows 15 minutes. 84876:May 4 08:31:06 seattle-vm-1-0 nsd: STATEMENT_TIMEOUT IS: 84877-May 4 08:31:06 seattle-vm-1-0 nsd: statement_timeout = 15min Then I send a query, and it generates a statement_timeout error after 10 seconds. The log has a CONTEXT which indicates a foreign key lookup was going on at the time which is fine... 2018-05-04 04:05:20 PDT [62028]: [82-1] ERROR: canceling statement due to statement timeout 2018-05-04 04:05:20 PDT [62028]: [83-1] CONTEXT: SQL statement "SELECT 1 FROM ONLY "public"."clients" x WHERE "c_id" OPERATOR(pg_catalog.=) $1 FOR KEY SHARE OF x" 2018-05-04 04:05:20 PDT [62028]: [84-1] STATEMENT: INSERT /* Is there anything I'm not thinking of?
