[PATCH] Make LNT compatible with PostgreSQL

[Yi Kong]

Hi Chris, Daniel,

After toying with the SQLite for a while, I found the existing
migration tools are too complicated to use and error prone, since some
db features we are using in SQLite are not supported in Postgres. I
suggest we add psql support now so that people can start using it if
starting anew or willing to migrate manually, and I will extend LNT to
support db migration(or merging) when I have time.

I'm not an expert in databases, any ideas would be appreciated.

Cheers,
-Yi
