NOTES
=====

Querying the tables of a database
---------------------------------

SELECT  relname 
  FROM pg_class 
  WHERE ( relkind = 'r') AND relname !~ '^pg_'
        AND relname !~ '^xinv[0-9]+' 
  ORDER BY relname;

und die infos dazu mit:

SELECT a.attnum, a.attname, t.typname, a.attlen, a.attnotnull 
  FROM pg_class c, pg_attribute a, pg_type t  
  WHERE c.relname = 'TABELLENNAME_HERE' AND 
        a.attnum > 0 AND a.attrelid = c.oid    
        AND a.atttypid = t.oid
  ORDER BY attnum;

Quering the databases of a server
---------------------------------

  SELECT * FROM pg_database

You need a database to connect PostgreSQL using libpq, but 'template1' should
always be available.

Fetch DB-names and their DBA:
  SELECT DISTINCT dbs.datname, users.usename 
  FROM pg_database dbs, pg_user users 
  WHERE dbs.datdba=users.usesysid
