Hello,
I'm trying to create an index:
create index search_idx on so2 using gin (to_tsvector('english',posts));
Looks like its running atleast for 8hours :( Totally I have 47M records in so2. Not sure why its taking so long time.
Any idea or tips to debug while the index creation is going on?
·“top -p <pid>” can show you if you are CPU or I/O bound.
·“perf top -p <pid>” on the backend that is doing the index creation is a good way to see where it is spending time.
Good luck!
Steven.
