@ -9,10 +9,10 @@ it on anything but an empty database, such as template1.
Uses pgeasy library.
Run on an empty database, it returns the system join relationships (shown
below for 7.0). Note that unexpected matches may indicate bogus entries
below for 7.1). Note that unexpected matches may indicate bogus entries
in system tables --- don't accept a peculiar match without question.
In particular, a field shown as joining to more than one target table is
probably messed up. In 7.0, the *only* field that should join to more
probably messed up. In 7.1, the *only* field that should join to more
than one target is pg_description.objoid. (Running make_oidjoins_check
is an easy way to spot fields joining to more than one table, BTW.)

(Ideally we'd just regenerate the script as part of the regression
tests themselves, but that seems too slow...)
NOTE: in 7.1, make_oidjoins_check produces two bogus join checks, one for
pg_database.datlastsysoid => pg_description.oid and one for
pg_class.relfilenode => pg_class.oid. These are artifacts and should not
be added to the oidjoins regress test.
