findoidjoins
-This program scans a database, and prints oid fields and the tables
-they join to. CAUTION: it is ver-r-r-y slow on a large database, or
-even a not-so-large one. We don't really recommend running it on
-anything but an empty database.
+This program scans a database, and prints oid fields (also regproc fields)
+and the tables they join to. CAUTION: it is ver-r-r-y slow on a large
+database, or even a not-so-large one. We don't really recommend running
+it on anything but an empty database.
It requires pgsql/contrib/pginterface to be compiled first.
-Run on an empty database, it returns the system join relationships
-(shown below for 6.5). 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.
+Run on an empty database, it returns the system join relationships (shown

+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 6.5, 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.)
The shell script make_oidjoins_check converts findoidjoins' output
into an SQL script that checks for dangling links (entries in an
-OID column that don't match any row in the expected table).
-The result of this script should be installed as the "oidjoins"
+OID or REGPROC column that don't match any row in the expected table).
+Note that fields joining to more than one table are NOT processed.
+
+The result of make_oidjoins_check should be installed as the "oidjoins"
regression test. The oidjoins test should be updated after any
revision in the patterns of cross-links between system tables.
(Ideally we'd just regenerate the script as part of the regression
