[postgis-users] How to get the size of a postgis table ?

[Aaron Koning]

------------------------------------------
Number of rows in the table:
     SELECT count(*) FROM <table_name>;

------------------------------------------
Size of files on disk - Method 1:
  - SELECT relpages * 8192 AS size_in_bytes FROM pg_class WHERE relnamespace
= (SELECT oid FROM pg_namespace WHERE nspname = '<schema_name>') AND relname
= '<table_name>'
  - Note: This value is only updated by the commands VACUUM, ANALYZE, and
CREATE INDEX.

------------------------------------------
Size of files on disk - Method 2:
  - Run this command to find the file node number for a particular table:
       SELECT relfilenode FROM pg_class WHERE relnamespace = (SELECT oid
FROM pg_namespace WHERE nspname = '<schema_name>') AND relname =
'<table_name>'
  - Then run ls -l <your postgres data directory>/base/<file node number>
       Example: ls -l /usr/local/pgsql/data/base/17384
