FreeBSD is OK if you are experienced. As a system it requires much more
maturity by the admin
than lets say Ubuntu which is targeted at a larger user base.
I'd say, explore your other Linux options first, since you already have
experience with Linux.
FreeBSD requires a much bigger learning curve

Hi,
A few questions about jsonb and hstore:
1. does jsonb replace hstore?
2. compatibility of jsonb <> hstore?
3. will the development of hstore continue?
4. is it recommended to use jsonb when planning new projects?
Thanks

Hi,
here is an example of a problem I encounter with json_populate_recordset
because it does not support nested object. Actually, I would prefer that it
ignores nested object rather than raise an error, as it fails on a key I
don't even want to use!
Here's the query:

hstore is a simple key-value model, while jsonb - richer document-based model.

As a side note, when we migrated the exact same pgsql 8.3 system from linux
kernel 2.6 to 3.6,
we experienced an almost dramatic slowdown by 6 times.
Linux Kernel's were known to have issues around those dates, i recall.
We had to set synchronous_commit to off, this gave a huge boost ,

That would be useful. :)
Would there be an aim of getting that in-core for 9.5?

hi,
Why is pg_restore trying to put stuff into the pg_catalog schema of all
places?
It's ignoring the schema specified in the pg_dump itself (`myschema`)
and even my search_path (`public`).

this is what you'll get. That's because what pg_dump e

Let's say I have function x() returning setof integers. I want to do

How can I do that?
