Right.

We lack any source-code-control history before 1996, so there's no
way to be sure who wrote that, unless you can identify some Berkeley
Postgres person with those initials.

There are other cases in the code with other initials. The practice
fell out of favor among the open-source PG community in the late 90s,
possibly because Tom Lockhart and I share the same initials so it
became completely impossible to avoid confusion :-(. I think the
surviving "tgl" comments in the code are mostly his, but I've not
counted carefully.
