Update of /home/cvs/cvsroot/gnucash/src/engine
In directory www.linas.org:/tmp/cvs-serv24361/src/engine

Modified Files:
	QueryNew.c 
Log Message:
	* src/backend/postgres/PostgresBackend.c (pgendEnable):
	Added ENTER/LEAVE statements

	* src/backend/postgres/escape.c: Adde gnc-engine-util.h,
	  and "module = MOD_BACKEND"
	- (sqlEscape_destroy): Added ENTER/LEAVE statemtents.

	* src/backend/postgres/gncquery.c (sql_Query_destroy): Added
	ENTER/LEAVE statements.

	* src/backend/postgres/putil.h: Cleaned up the formatting on the
	SEND/FINISH/EXEC/GET_RESULT macros.  Changed them to use
	PQresultErrorMessage where possible. Made them all set the Backend
	error message string.  Removed the PQfinish() calls, and setting
	be->connection to NULL.  Reasoning: if a malformed query fails, there is
	no reason to close the connection.  If an update/insert fails,
	again, there is no need to close the connection.  The user should
	be presented an error message and respond appropriately.  If
	a update/insert/delete fails, then generally the transaction is
	rolled back to the last BEGIN, thereby preventing data corruption.

	* src/engine/QueryNew.c (gncQueryPrint): Check that q is not NULL
	prior to processing it.
