This utility allows administrators to view the file structure used by PostgreSQL. Databases are placed in directories based on their OIDs in pg_database, and the tables in that directory are named by original OIDs, stored in pg_class.relfilenode. Oid2name connects to the database and extracts the OID and table name information. --------------------------------------------------------------------------- It can be used in four ways: oid2name This will connect to the template1 database and display all databases in the system: $ oid2name All databases: --------------------------------- 18720 = test1 1 = template1 18719 = template0 18721 = test 18735 = postgres 18736 = cssi oid2name -d test [-x] This connects to the database test and shows all tables and their OIDs: $ oid2name -d test All tables from database "test": --------------------------------- 18766 = dns 18737 = ips 18722 = testdate oid2name -d test -o 18737 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 respectively: $ oid2name -d test -o 18737 Tablename of oid 18737 from database "test": --------------------------------- 18737 = ips $ oid2name -d test -t testdate Oid of table testdate from database "test": --------------------------------- 18722 = testdate Keep in mind tables over one gigabyte will be split into separate files with numeric file extensions. --------------------------------------------------------------------------- Sample session: $ cd /u/pg/data/base $ oid2name All databases: --------------------------------- 16817 = test2 16578 = x 16756 = test 1 = template1 16569 = template0 16818 = test3 16811 = floattest $ cd 16756 $ ls 1873* 18730 18731 18732 18735 18736 18737 18738 18739 $ oid2name -d test -o 18737 Tablename of oid 18737 from database "test": --------------------------------- 18737 = ips $ oid2name -d test -t ips Oid of table ips from database "test": --------------------------------- 18737 = ips $ # show disk space for every db object $ du * | while read SIZE OID > do > echo "$SIZE `oid2name -q -d test -o $OID`" > done 24 18737 = ips 36 18722 = cities ... $ # same as above, but sort by largest first $ du * | while read SIZE OID > do > echo "$SIZE `oid2name -q -d test -o $OID`" > done | > sort -rn 2048 19324 = bigtable 1950 23903 = customers ... $ # show disk usage per database $ cd /u/pg/data/base $ du -s * | > while read SIZE OID > do > echo "$SIZE `aspg oid2name -q | grep ^$OID' '`" > done | > sort -rn 2256 18721 = test 2135 18735 = postgres .. This can be done in psql with: test=> SELECT relpages, relfilenode, relname FROM pg_class ORDER BY relpages DESC; Each page is typically 8k. Relpages is updated by VACUUM. --------------------------------------------------------------------------- Mail me with any problems or additions you would like to see.
