I have Postgresql DB on my pc and I'm trying to connect different database application to Postgresql but before that(An research issue), for each application, I need to see all the input parameter and all the queries corresponding to those input parameter that application can do.
How?
Look in the code of every application and see what calls are being made. In addition figure out all the parameter values that can be sent based on an almost infinite combination of characters and numbers the user can select from.
Or to remain sane turn on postgresql logging and let the users do their thing and analyse what calls are being made.
