This gets rid of the code that issued separate queries to retrieve the partitioning parent-child relationship, parent partition key, and child partition bound information. With this patch, the information is retrieved instead using the queries issued from getTables() and getInherits(), which is both more efficient than the previous approach and doesn't require any new code. Since the partitioning parent-child relationship is now retrieved with the same old code that handles inheritance, partition attributes receive a proper flagInhAttrs() treatment (that it didn't receive before), which is needed so that the inherited NOT NULL constraints are not emitted if we already emitted it for the parent. Also, fix a bug in pg_dump's --binary-upgrade code, which caused pg_dump to emit invalid command to attach a partition to its parent. Author: Amit Langote, with some additional changes by me.
