Is there actually a use-case for that? It seems like mostly pointless

Hi,
I was looking to start development on the following TODO entry.
Add a separate TRUNCATE permission
Currently only the owner can TRUNCATE a table because triggers are not called,
and the table is locked in exclusive mode.
Does anyone have any objections? Looks like there is a change freez
I know we have talked about how to avoid legal email signatures on this

emails with a legal signature. I know I am less likely to reply to such

If enough people do that, it might coerce people to avoid them, and

Yeah. Another problem with using their original source code is that
running the Snowball compiler during build would not work for

Works fine when using V3 frontend protocol. The old protocol for it
isn't 8-bit-clean.

Or (rather) the log base 10 of Stirling's formula. The n! estimator
