Ah.  Go to the command line.  Switch to the postgres user (whoever owns
 the PostgreSQL directories).  Run:
createlang plpgsql template1

Additionally, if you have already created other databases, you need to
 run
createlang plpgsql database-name
for each database as the database owner (the user who created the
 database).

Don't designate VARCHAR sizes when using them as function variables.
  Just "VARCHAR".

I highly reccommend that you consider changing your coding practices.
  I think that you will find in PL/pgSQL that mixed-case variable names
 are more trouble than they're worth.

Hmmm... you've got a bunch of other syntax problems here (too many to
 list).  Have you read the full documentation for PL/pgSQL?   Also
 consult some Oracle PL/SQL books; PL/pgSQL was written to be
 syntax-compatible with PL/SQL.

Tell you what ... if we can boast online that Macy's uses PostgreSQL,
 you may be able to get some one-on-one online free support.
