Petition: Treat #!... shebangs as comments

Could we please have the PostgreSQL lexer treat #!... on the first line of
a file as a comment? This would enable .psql scripts to be run with
dot-slash notation preferred by many unix users:

./script.psql

While still allowing the traditional (and Windows compatible) style:

psql -f script.psql
