Before we even get there we need agreement on exactly what it means :-)
Seems like the best place for the settings might be pg_hba.conf.
Say we have a new keyword "limit" there. Here are the possibilities (I
think):
case 1 - limit username's connections to dbname:
limit dbname username n
case2 - limit username's connections regardless of database:
limit all username n
case 3 - limit all users' connections to dbname:
limit dbname all n
case 4 - limit username's connections to any particular database:
limit any username n
case 5 - limit all users' connections to any particular database:
limit any all n
case 6 - limit all users' connections regardless of database:
limit all all n
Would we want to bother about cases 4 and 5? Are the semantics of case 6
what we want?
Once the behaviour is agreed, (based on my recent experience) I think
this is something that might well be attempted by someone new to Pg
development. If you ask questions you will get plenty of help.
