Thanks!!!  That fixed our problem!  I should have stated that my source was
the result of an ecpg run.  We used the preprocessor to make some source
that we could manipulate, and never went back to the earlier source code.
Man this is great.

Thanks again!
Bruce

The function listed below is not an embedded sql function as preprocessed by
ecpg. It only uses libecpg. Or is this the result of an ecpg run?

ECPGconnect is used to connect to a database. So you open a connection to DB
currentuser everytime you call this function.

This only commits the transaction but does not disconnect from the database.
For that you need a call to ECPGfinish as done in ECPGdisconnect.
