Re: Lock contention in TransactionIdIsInProgress()
Hi Jeff,
We have encountered same problem as you (in 9.5.4), it seems that so far it
hasn’t been ported back from 9.6, but if you take this commit and apply it
to 9.5 source codes, it seems to be working
But anyway, does anybody knows plans about backporting this to 9.5 official
way?
Regards
Tomas

Won't happen. Only bugs get ported back, and performance enhancements
generally don't qualify (in very exceptional cases they might but this
issue is a routine performance enhancement). Basically you have to
decide to update or stay with 9.5.

Another possibility is to patch and build yourself Postgres if you are
still willing to use that with a given version. But as that's actually
forking the upstream version, it won't be supported by community.

Hopefully we don't port bugs back all that often.
