I'm trying to code a problem where a set of options can be expressed in
a data column like "10111011", a bit string.
Each position is atomic and represents a certain setting within the set,
thus: "00100000" would return TRUE if OR'd with "10111011", since the
3'rd position matches in both sets.
While I could manually retrieve N records and iterate through them in
whatever programming language (or possibly a plpgsql function), is there
a way I could natively do this in a WHERE clause in my query?
Looking through the idocs, I could not immediately find a way around
this issue. Any pointers to documentation (or perhaps another way to
implement this issue) would be very helpful.
