also don't forget the -1 option to psql, which will wrap all your
commands in a transaction, and:
\set ON_ERROR_STOP
which will abort if there's an error. either put this in all your
scripts, your .psqlrc, or echo it into psql like this:
cat <(echo "\set ON_ERROR_STOP")
module1.sql \
module2.sql \
module_etc.sql \
| psql -1
you'll want to abort on error just to avoid the chance that a token in
your script will inadvertently close the transaction and cause a bunch
of garbage to be committed in the database -- this is likely to happen
say if you have a quotation error on function body.
