All, Currently, the only way for admin scripts to get individual data items out of pg_controldata (such as the next XID or the catalog version) is via grep and regex. Given that people are going to be relying on some of this data for replication admin in the future, it seems past time to have a form of pg_controldata which either outputs machine-readable text (XML or JSON), or (my preference) takes options to output just the invididual items, e.g.
pg_controldata --catalog_version Even better would be the ability to get everything which is in pg_controldata currently as part of a system view in a running PostgreSQL; I can get most of them, but certainly not all.
