List all sequences in a Postgres db 8.1 with SQL

Question

I\'m converting a db from postgres to mysql.

Since i cannot find a tool that does the trick itself, i\'m going to convert all postgres sequences to autoincrement id

Answer 1

This statement lists the table and column that is associated with each sequence:

Code:

    SELECT t.relname as related_table, 
           a.attname as related_column,
           s.relname as sequence_name
    FROM pg_class s 
      JOIN pg_depend d ON d.objid = s.oid 
      JOIN pg_class t ON d.objid = s.oid AND d.refobjid = t.oid 
      JOIN pg_attribute a ON (d.refobjid, d.refobjsubid) = (a.attrelid, a.attnum)
      JOIN pg_namespace n ON n.oid = s.relnamespace 
    WHERE s.relkind     = 'S' 

  AND n.nspname     = 'public'
