I've been stumped as to how to call psql from the command line without it
prompting me for a password. Is there a enviornoment variable I can specify for
the password or something I can place in .pgsql? I could write a perl wrapper
around it, but I've been wondering how I can call psql -c without it prompting
me. Is it possible?

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
