Fix failed update with parallel workers #3288

mfundul · 2021-05-27T19:59:26Z

When executing "ALTER EXTENSION timescaledb UPDATE TO ..." it will fail
if parallel workers spawn for the update itself. Add the appropriate
check to fix this.

Change looks fine, but you need to add an update test to test this. AIUI, you had a reliable way to reproduce it by changing the parameters for an instance?

Change looks fine, but you need to add an update test to test this. AIUI, you had a reliable way to reproduce it by changing the parameters for an instance?

It can be reproduced by following the steps of #3286. I guess it can be done in a test as well.

When executing "ALTER EXTENSION timescaledb UPDATE TO ..." it will fail if parallel workers spawn for the update itself. Disable parallel execution during the update.
