I'm working on completing Heikki's patch for streaming base backups,
and have run into a problem:
In order to dump all tablespaces properly, I have to know where they
are (d'uh). In order to do that, I need to scan pg_tablespace.
However, scanning that from walsender gives me:
FATAL: cannot read pg_class without having selected a database
Which means I somehow have to get pg_tablespace into the cache without
reading pg_class, I guess. Similar to how we do for pg_database for
example.
Can someone throw me a pointer or two on how to actually do that? :-)
Am I correct in assuming I need to add it to
RelationCacheInitializePhase2(), and to do that, need to figure out
how to define a TableSpaceRelation_Rowtype_Id in the headers? Or is
there an easier way I'm missing?
