With version 7.1 of PostgreSQL server, the old naming scheme for
|
|
databases and tables (in $PGDATA/base) has changed. The databases
|
|
are put in folders for their OID in pg_database and the tables in
|
|
that folder are named for their OIDs in pg_class. This app connects
|
|
to the database (you can specify host, port, user, pass etc to
|
|
connect to a host other than localhost) and extracts the OID and
|
|
table name information. It has 4 ways it can be run:
|
|
|
|
pg_oid2name
|
|
|
|
This will connect to the template1 database and display all databases
|
|
in the system.
|
|
|
|
$ ./pg_oid2name
|
|
All databases:
|
|
---------------------------------
|
|
18720 = test1
|
|
1 = template1
|
|
18719 = template0
|
|
18721 = test
|
|
18735 = postgres
|
|
18736 = cssi
|
|
|
|
pg_oid2name -d test [-x]
|
|
|
|
This connects to the database test and shows all tables and their OIDs.
|
|
|
|
$ ./pg_oid2name -d test
|
|
All tables from database "test":
|
|
---------------------------------
|
|
18766 = dns
|
|
18737 = ips
|
|
18722 = testdate
|
|
|
|
pg_oid2name -d test -o 18737 or
|
|
pg_oid2name -d test -t testdate
|
|
|
|
This will connect to the database test and display the table name for oid
|
|
18737 and the oid for table name testdate respectivly.
|
|
|
|
$ ./pg_oid2name -d test -o 18737
|
|
Tablename of oid 18737 from database "test":
|
|
---------------------------------
|
|
18737 = ips
|
|
|
|
|
|
$ ./pg_oid2name -d test -t testdate
|
|
Oid of table testdate from database "test":
|
|
_______________________________
|
|
18722 = testdate
|
|
|
|
|
|
There should be a decent amount of error handling in the app, a lot of it
|
|
dealt with via the postgres function calls.
|
|
|
|
$ ./pg_oid2name -d nothere -t testdate
|
|
Oid of table testdate from database "nothere":
|
|
_______________________________
|
|
Connection to database 'nothere' failed.
|
|
FATAL 1: Database "nothere" does not exist in the system catalog.
|
|
|
|
$ ./pg_oid2name -d test -t nothere
|
|
Oid of table nothere from database "test":
|
|
_______________________________
|
|
No tables with that name found
