Rails, PostgreSQL - how to count the number of tags?

I have these DB tables:

taggings

id | integer | not null default nextval('taggings_id_seq'::regclass) | plain | tag_id | integer | | plain | taggable_id | integer | | plain | taggable_type | character varying(255) | | extended | tagger_id | integer | | plain | tagger_type | character varying(255) | | extended | context | character varying(128) | | extended | created_at | timestamp without time zone | | plain |

tags

id | integer | not null default nextval('tags_id_seq'::regclass) | plain | name | character varying(255) | | extended |

These tables are created by the acts-as-taggable-on gem.

I am trying to get the count of most used tags that are stored in the table taggings, but I have no idea how to get them...

Could anyone give me some tip or link, how to get that?
