Per https://postgr.es/m/CAEepm=11ma_Z1HoPxPcSCANnh5ykHORa=hca1u1v1+5s_jw...@mail.gmail.com it seems that the dsm.c API is a bit inconvenient right now. I proposed in the first patch in that thread to change the API so that a segment is marked as "pinned" if created with no ResourceOwner set as current; which is essentially the same as creating a fake one, then marking the segment as pinned.
Thomas agrees with me, so I propose this patch as preparatory work for the autovacuum/BRIN stuff I'm interested in. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
