PG 15 and up report the syntax error differently.

regression=# set foo = 15min;
ERROR: trailing junk after numeric literal at or near "15min"
LINE 1: set foo = 15min;
^

In v14 that'd look like

regression=# set foo = 15min;
ERROR: syntax error at or near "min"
LINE 1: set foo = 15min;
^

There are variants of this (lack of space between a number and an
identifier) that will be rejected by 15+ although older versions
accepted them. But in a SET command I think no version will take it.
