[Xen-devel] [OSSTEST PATCH 13/33] Database locking: Tcl: Use db-execute

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

Replace open-coded uses of pg_execute dbh STMT with
jobdb::db-execute STMT.

The only functional change is that if OSSTEST_TCL_JOBDB_DEBUG is set,
there will be debugging output.

But we are going to want to make db-execute do something more
complicated involving pg_exec.
