Is your file "friendly" or arbitrary? With DBI, you can exe-
cute several commands in one do() call, but you cannot split
one command across several calls. The PostgreSQL frontend/
backend protocol seems to allow that by a cursory look, but
that's *very* far from JDBC/ODBC/DBI.

  If there are no guarantees on the format of your file, I
would try to adapt psql's psqlscan.l & Co.
