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.

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

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:

SSDs are ridiculously cheap when you consider the performance
difference.
It might be tempting to use a consumer-grade SSD due to the significant
cost savings, but the money saved is vapor. They may be OK for a dev
