It's been perfectly clear since day one, and was reiterated as recently
as today
http://archives.postgresql.org/message-id/4B21757E.7090806@2ndquadrant.com
that what the security community wants is row-level security. The
proposals to make SEPostgres drive regular SQL permissions never came
out of anyone from that side, they were proposed by PG people looking
for a manageable first step. Whatever you might believe about the
potential market for SEPostgres, you should divide by about a hundred
as long as it's only an alternate interface to SQL permissions. See
particularly here:
http://wiki.postgresql.org/wiki/SEPostgreSQL_Review_at_the_BWPUG#Revisiting_row-level_security
"Without it, it's questionable whether committing the existing
stripped-down patch really accomplishes anything" --- how much
clearer can they be?
If you're not prepared to assume that we're going to do row level
security, it's not apparent why we should be embarking on this course
at all. And if you do assume that, I strongly believe that my effort
estimate above is on the optimistic side.
