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

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