Add db:charset task support for PostgreSQL

Solid patch, but there are a couple of minor complains. Firstly, it would be nice to format the SQL consistently, so "SELECT", "FROM", "WHERE" should all be capitalized. And secondly, please don't add empty lines and trailing whitespace (git should also warn about it).

+1 if those two are adressed

Done. I've uppercased all the SQL commands and eliminated the unnecesary newlines.

New patch uploaded.

Thanks.
