psqlrc

By default psql renders `NULL' values as empty strings. This makes it harder to "see" if a column is `NULL' or an empty string, so I like to have a different representation for NULLs

\pset null '⊥'

I also use to connect to databases on different hosts, so to be extra sure that I'm connected to the right one I'd like for psql to dump the connection info at the start

\conninfo
