The PostgreSQL "COPY" command is very efficient at
bulk loading, but has restrictive requirements as to
the data formats that it will accept.

I haven't tried this one, but it might work for you:

Otherwise your best alternative is probably to write a
custom script using something like Perl, TCL, Awk or
Sed to edit your data, which can then be piped to
COPY.  Something like:
perlscript datafile | psql -c "copy table from stdin"

You can read about "COPY" in the "SQL Commands"
section of the manual.
