Wrong messages running on Windows

Hi! I've been using the PostgreSQL database in Windows since the Beta2-dev3=
, and it had a bug I didn't report. I've just downloaded the rc2, and unins=
talled my previous version, and installed the newest one, and it still have=
 the same bug.

When executing the command line functions psql, pg_dump, createuser, create=
db, dropuser, dropdb, they output a message in the format:

could not find a "functionname" to execute

where functionname is the name of the function i'm using.

Hope you can help me with this "bug" (if it is), so PostgreSQL can continue=
 improving.

Thanks a lot.

P.S.: I'm running Windows 2000 Professional with Service Pack 4, with all c=
ritical updates installed. My OS version is in Spanish (and most of my soft=
ware too). My computer is an Intel Celeron 600 MHz, 256 MB RAM, 40 GB HDD (=
with 4 partitions, all in NTFS).=
