PostgreSQL uses the spaces inconsistently, though. pg_size_pretty uses spaces:
# select pg_size_pretty((2^20)::bigint);
SHOW does not:
# show work_mem;
The SHOW output is formatted by _ShowOption() using 'INT64_FORMAT "%s"',
via convert_from_base_unit(). The latter has a comment attached...
* Convert a value in some base unit to a human-friendly unit. The output
* unit is chosen so that it's the greatest unit that can represent the value
* without loss. For example, if the base unit is GUC_UNIT_KB, 1024 is
* converted to 1 MB, but 1025 is represented as 1025 kB.
... where the spaces are present again.
General typesetting standard seems to be "1 MB", i.e. to include a
space between value and unit. (This would also be my preference.)
Opinions? (I'd opt to insert spaces in the docs now, and then see if
inserting a space in the SHOW output is acceptable for 10.0.)
