------snip------
temp_buffers (integer):
Sets the maximum number of temporary buffers used by each database session

Are we setting the maximum number of buffers or the maximum total size of
the buffers?

Yeah, it's ambiguous. If you give it without units, it's the number of
buffers; otherwise it's the size. The docs were updated in version 12
to include this phrase: "If this value is specified without units, it is
taken as blocks, that is BLCKSZ bytes, typically 8kB."
