Postgres Transaction timeout when creating a foreign key

Question

I am trying to run the following statement in postgres : "ALTER TABLE "public"."opportunity_talentconnection" ADD CONSTRAINT "fk_connector" FOREIGN KEY ("connector_id") REFERENCES "public"."profiles_connector"("id")"

And I am getting a Transaction Timeout after 30 seconds. opportunity_talentconnection is a brand new table and profiles_connector currently have 2341 entries.

The call was failling using django-south, so I tried to run it directly in postgres but I got the same result. I try to manually create the foreign key constraint with the GUI (phpPgAdmin) and I got the same result again.

Any idea why it is failling while it worked in other environnement also using postgres?

You may set the timeout value on a per-session basis with this command,

PGOPTIONS="-c statement_timeout=60000" psql -U dbname dbname

Thanks for the tip. But the actual issue is the a simple alter table results in a transaction timeout. I stumble onto another problem I'm getting Transaction timeout when dropping tables to . I tried something as simple as << DROP TABLE "opportunity_jobopportunity_connectors"; >> and it failed with a Transaction Timeout too. But when I do a TRUNCATE it works. My guess is that some table logs are full on the webfaction servers;

Please submit a support ticket so we can look at the issue. Include your permission to or not to drop the table.
