findoidjoins
|
|
|
|
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, 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
|
|
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
|
|
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 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
|
|
tests themselves, but that seems too slow...)
