Make column privileges matchable/callable #1
Description
Rather than forcing users to enumerate every possible column name in the schema, column checks could be checked against a pattern (such as a prefix or regex) or even checked via a (lambda) function.
In this way, a USER1 could create and query all columns that their pattern matches (which might be the prefix '' or the pattern r'*').
USER2 could create and query all columns prefixed with 'quant_' and 'user_', but not '_dev'
USER3 could create and query only columns prefixed with 'user_'
This could extend beyond pattern matching to an arbitrary evaluation function, with all the performance and security problems contained therein.
Thoughts, @erikerlandson ?
