Hi.
Is spaces is necessary in text presentation of JSONB?
In my data resulting text contains ~12% of spaces.
I'm developing web application, and want to get json-string from pg and
send it to browser without repacking.

Hello,
we have a setup with Postgres 9.3.4 running on Ubuntu (don't know the exact
version) using streaming replication with a hot standby and pgPool 3.3.3 as a
loadbalancer in front of the two Postgres servers.
While running automated tests we noticed that despite the fact that replication

IMHO, prettification is useful only for debugging.
It would be nice to have a session variable for the debug output with

Hi all,
I continue to bang along towards a binding of the spgist api from a run-time

To avoid complication, I am actually not doing any postgis code at this point,
just copying the internal point quadtree implementation and seeing if I can get
it to turn over.

I think your problem is not relevant to pgpool-II.
PostgreSQL's synchronous replication is actually not synchronous
(it's confusing but the naming was developer's decision). Primary
server sends the committed transaction's WAL record to standby and
wait for it is written to the standby's WAL file
Still no go. I actually tried a bunch of different selectivity functions too,
and the planner correctly used them to estimate the number of potential
returned functions, but in no case did the index actually kick in, no matter
how selective I made the operator appear.

Yep, that was a typo (or, rather, an unpushed commit). And yep, the lack of a
