Get IP addresses from tsvectors - Mailing list pgsql-general

Greetings,

I have a table with a column with type tsvector. It contains the
result of to_tsvector() of varchar field in the table. What I'd like
to do is be able to search through the table and find all of the
distinct IP addresses. Any idea how to turn:

SELECT message_index_col FROM systemevents LIMIT 10;
                                                        message_index_col
