The EPSG folks now provide SQL dumps of their database with the intent
that it could be easily loaded into a variety of databases.  I would suggest
you fetch those and try loading them into postgresql.

There is no need for the PostGIS team itself to provide
this sort of auxilary coordinate system table support directly.
They have quite a bit on their table already. :-)
