Thread: Error Messages

We have postrges 6.3 installed running on Linux
and using DBD and DBI. I am writing perl programs
to access the data base and would like to replace
the standard error messages with more 'user friendly'
messages. For example instead of "Bad date external
representation". I would like to say "Invalid date".
Is there any way to obtain the list of
possible messages produced by each sql command
so I can set up a table of replacement messages?
