README.findoidjoins
findoidjoins This program scans a database and prints oid fields (also reg* fields) and the tables they join to. We don't really recommend running it on anything but an empty database, such as template1; else it's likely to be very slow. Run on an empty database, it returns the system join relationships (shown below for 8.0). 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 8.0, the *only* fields that should join to more than one target are pg_description.objoid, pg_depend.objid, and pg_depend.refobjid. (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 or REG* 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 tests themselves, but that seems too slow...) NOTE: in 8.0, make_oidjoins_check produces one bogus join check: Join pg_catalog.pg_class.relfilenode => pg_catalog.pg_class.oid This is an artifact and should not be added to the oidjoins regress test. Also beware of any claim that pg_database.datlastsysoid joins to anything; this does not actually happen in 8.0, but it did happen before and might happen again in future, depending on what operation initdb does last. --------------------------------------------------------------------------- Join pg_catalog.pg_aggregate.aggfnoid => pg_catalog.pg_proc.oid Join pg_catalog.pg_aggregate.aggtransfn =>
