Retire findoidjoins.
In the wake of commit 62f34097c, we no longer need this tool. Discussion: https://postgr.es/m/3240355.1612129197@sss.pgh.pa.us

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 11devel as of 2018-05-07).
|
|
||||||
|
|
||||||
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.
|
|
||||||
Currently, 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, pg_shdepend.refobjid,
|
|
||||||
and pg_init_privs.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 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: currently, 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 regression test.
|
|
||||||
You might also get output for pg_shdepend.refobjid and pg_shdescription.objoid,
|
|
||||||
neither of which should be added to the regression test.
|
|
||||||
|
|
||||||
In short, the procedure is:
|
|
||||||
|
|
||||||
1. make installcheck in src/test/regress
|
|
||||||
2. cd here, make
|
|
||||||
3. ./findoidjoins regression >foj.out
|
|
||||||
4. ./make_oidjoins_check foj.out >oidjoins.sql
|
|
||||||
5. paste foj.out below, removing the entries reported as duplicative
|
|
||||||
by make_oidjoins_check or described as bogus above
|
|
||||||
6. remove bogus tests in oidjoins.sql as per above
|
|
||||||
7. copy oidjoins.sql to src/test/regress/sql/,
|
|
||||||
and update oidjoins.out to match.
|
|
||||||
8. Review diffs to ensure they correspond to new catalog relationships,
|
|
||||||
then commit. (Sometimes, a pre-existing catalog relationship might
|
|
||||||
become newly visible here as a result of the regression tests populating
|
|
||||||
a catalog they didn't before. That's OK too.)
