Query Deparsing Support
The DDL deparse support that just landed looks impressive, but I’ve needed query deparsing for some time now. Within pg_shard <https://github.com/citusdata/pg_shard> we took the fast-and-dirty approach of merging in a modified ruleutils.c, though I’d (obviously) like to get away from that.
Many of ruleutils.c’s functions already have a public interface; would there be any objection to exposing get_query_def to provide a way to turn a Query back into an SQL string?
A more structured approach analogous to the new DDL stuff would make my life easier, but simply having the Query-to-SQL function would be a huge improvement for now.
I trawled through the archives but couldn’t find any discussion of why this function was kept static.
