= Postgres Sequence Support

Easy manipulation of PostgreSQL sequences from ActiveRecord.

== Examples

  User.next_id              # => 1

  User.current_id           # => 1

  c = ActiveRecord::Base.connection

  c.set_sequence('users_id_seq', 1000)

  c.next_in_sequence('users_id_seq')      # => 1001

  

  # Note : create sequence don't do anything if sequence already exists

  c.create_sequence('my_own_seq')

  c.next_in_sequence('my_own_seq')        # => 1

  

  # You can specify sequence start

  c.create_sequence('my_own_seq', 1001)

  c.next_in_sequence('my_own_seq')        # => 1001

  

  # Check if sequence exists

  c.sequence_exists?('my_own_seq')        # => true

  c.sequence_exists?('my_other_seq')      # => false

  

  # Drop sequence if it exists

  c.drop_sequence('my_own_seq')
