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

The following query gives names of all sequences.

SELECT c.relname FROM pg_class c WHERE c.relkind = 'S';

Typically a sequence is named as ${table}_id_seq. Simple regex pattern matching will give you the table name.

To get last value of a sequence use the following query:

SELECT last_value FROM test_id_seq;
