My lack of explanation caused the confusion, sorry.
Your point is true.
"DECLARE STATEMENT" is declarative ,not function in .pgc file.

I wanted to say that in order to use the connection pointed 
by the DECLARE STATEMENT some functions like ECPGdo() would be modified or
new function would be added under the directory ecpglib/.

This modification or new function will be used to get the connection by
