In MSSQL, I have a dozen or so databases that rely on some shared tables (states, species lists, for example). I put the shared tables in a db called Common. To query them, mssql allows:
select statename, stateabbrev from common.dbo.statelist S inner join mytable on S.stateabbrev = mytable.stateabbrev
I'm not asking for PostgreSQL to be more like mssql, but I would like to share some lookup tables among applications & databases. In looking through the help, it appears from the "Schemas" help page (http://www.postgresql.org/docs/8.3/static/ddl-schemas.html) that PostgreSQL uses a single database per connection (pgAdmin client, web client). Is there a best practice or recommendation page for how to handle this sharing of a common lookup table? Or a help page I missed that discusses it?
Right now I see my options as: a) put all applications for which I use PostgreSQL into one database, but different schemas. b) use a client tool to make a separate connection and create a join afterwards
