List tables in reverse dependancy order

I am not sure if this is the appropriate list -- please point me at the correct one if not.

I'm trying to create a procedure that would let me retrieve a list of tables and views in a database that will be used to control the order in which lookup data is created/loaded. So, much simplified, if table references table B, which in turn references table A, we want output to list table A, B and C in that order.

I'm sure that this exists -- the pg_dump command must use some similar algorithm to decide in which order to load tables, but I can't see to puzzle this out.

Can anyone provide me with some clues, appropriate RTFM references, etc. ?

TIA,
