Hello everybody out there using PostgreSQL, After having read the official documentation and having done extensive web search, I'm wondering how to perform something like a SELF LEFT OUTER JOIN in PostgreSQL, i.e. a SELF JOIN on a table containing NULL values in one of the columns to join.
Something like this? - select.... from my_table a left join my_table b on (a.my_column = b.my_column) ... Would this do it?
