2020-05-15Rename assorted LWLock tranches.Tom Lane
Choose names that fit into the conventions for wait event names (particularly, that multi-word names are in the style MultiWordName) and hopefully convey more information to non-hacker users than the previous names did. Also rename SerializablePredicateLockListLock to SerializablePredicateListLock; the old name was long enough to cause table formatting problems, plus the double occurrence of "Lock" seems confusing/error-prone. Also change a couple of particularly opaque LWLock field names. Discussion: https://postgr.es/m/28683.1589405363@sss.pgh.pa.us

2017-09-14Add support for coordinating record typmods among parallel workers.Andres Freund
Tuples can have type RECORDOID and a typmod number that identifies a blessed TupleDesc in a backend-private cache. To support the sharing of such tuples through shared memory and temporary files, provide a typmod registry in shared memory. To achieve that, introduce per-session DSM segments, created on demand when a backend first runs a parallel query. The per-session DSM segment has a table-of-contents just like the per-query DSM segment, and initially the contents are a shared record typmod registry and a DSA area to provide the space it needs to grow. State relating to the current session is accessed via a Session object reached through global variable CurrentSession that may require significant redesign further down the road as we figure out what else needs to be shared or remodelled.
