Thread: Commit timestamp abbreviations
I noticed this when looking at the allocated shared memory structures in head: shared memory alignment 64-byte of CommitTs Ctl: 0shared memory alignment 64-byte of CommitTs shared: 0 I thought we got rid of the idea that 'Ts' means timestamp. Was this part forgotten? -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + Everyone has their own god. +

I remember the issue of using _ts and 'ts' inconsistently, and I thought we were going to spell out timestamp in more places, but maybe I am remembering incorrectly. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + Everyone has their own god. +
