src/tools/findoidjoins/README
findoidjoins
============
This program scans a database and prints oid fields (also reg* fields)
and the tables they join to. It is normally used to check the system
catalog join relationships (shown below for 9.2devel as of 2011-11-14).
Historically this has been run against an empty database such as template1,
but there's a problem with that approach: some of the catalogs are empty
and so their joining columns won't show up in the output. Current practice
is to run it against the regression-test database, which populates the
catalogs in interesting ways.
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 9.2devel, the *only* fields that should join to more than one target
table are pg_description.objoid, pg_depend.objid, pg_depend.refobjid,
pg_shdescription.objoid, pg_shdepend.objid, and pg_shdepend.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,
just reported as linking to more than one table.
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.
(Typically we update it at the end of each development cycle.)
NOTE: as of 9.2devel, make_oidjoins_check produces two bogus join checks:
Join pg_catalog.pg_class.relfilenode => pg_catalog.pg_class.oid
Join pg_catalog.pg_database.datlastsysoid => pg_catalog.pg_database.oid
These are artifacts and should not be added to the oidjoins regress test.
You might also get output for pg_shdepend.refobjid and pg_shdescription.objoid,
neither of which should be added to the regress test.
