Hello,
Our postgresql logs are getting filled with warnings:
LOG: picksplit method for column COLUMN_IDX of index INDEX_NAME
doesn't support secondary split
We are using gist indexes on integer, timestamp, and Postgis geometry.
Is there a way to work around this problem?
Thank You,
Oleg Mürk

A similar complaint from a long time ago. It looks like the conclusion
was to demote that to a DEBUG1 message, which won't clutter your logs.
It doesn't indicate a real problem. It's essentially saying that PostGIS
is missing out on a potential optimization, which is not something you
can easily fix. It's also not very well documented, unfortunately, so
it's not something the PostGIS folks can fix easily, either. I brought
this up on -hackers, so hopefully it will be resolved.
In the meantime, you're stuck with the messages cluttering your
logfiles.
