If you want to use the \d command in a C program, link your program to libpq and grab the C source code for the \d command from psql. Also, if you just need to know the SQL used to generate the command output you can use the following command: \set ECHO_HIDDEN 1 Now all the SQL used in psql commands will be displayed. The SQL for the \d command is === psql 5 === \d ********* QUERY ********** SELECT n.nspname as "Schema", c.relname as "Name", CASE c.relkind WHEN 'r' THEN 'table' WHEN 'v' THEN 'view' WHEN 'i' THEN 'index' WHEN 'S' THEN 'sequence' WHEN 's' THEN 'special' END as "Type", r.rolname as "Owner" FROM pg_catalog.pg_class c JOIN pg_catalog.pg_roles r ON r.oid = c.relowner LEFT JOIN pg_catalog.pg_namespace n ONn.oid = c.relnamespace WHERE c.relkind IN ('r','v','S','') AND n.nspname NOT IN ('pg_catalog', 'pg_toast') AND pg_catalog.pg_table_is_visible(c.oid) ORDER BY 1,2; ************************** List of relations Schema | Name | Type | Owner --------+--------------------------+----------+------- public | barcode | table | user1 public | foo | table | user1 public | foo_a_seq | sequence | user1 (3 rows) John DeSoi, Ph.D. http://pgedit.com/ Power Tools for PostgreSQL
