[pgpool-hackers: 3804] Re: [pgpool-committers: 7084] pgpool: Fix relcache query sometimes sent to other than primary.

[Tatsuo Ishii]

Hi,

I have fixed a nasty bug in handling relcache.  I thought that relcache
queries are always sent to the primary server in streaming replication
mode but actually they were not. So I fixed it and pushed to from
master to 3.5 stable branches.

Best regards,
