OK, I have simplified the patch. It doesn't use any new computations
but just displays them differently. The output is now:
INFO: free space map contains information about:
INFO: 49 relations, limit 1000 relations
INFO: 35

The original comment of why we are safe without protection of critical
section is confusing.
I thought your version was even more so :-(. I've applied the attached
patch instead.

Here is a reformatting of the VACUUM VERBOSE FSM output so it outputs
from a single INFO output command:
INFO: free space map contains information about:
49 relations, limit 1000 relations
35 pages with free space, 784 pages (with overhead)
784 pages

Well, the number you highlighted might not equal the number on the next
line if you don't have enough entries to store all the free space, e.g.:
INFO: free space map contains information about:
49 relations, limit

What goes in the remaining 5276 (19300-14024) page entries anyway?
That's overhead forced by the quantized allocation of FSM slots.

Should the memory used line be a hint?
Well, the main message should fit on one line, and the rest is either
hint or detail. In this case detail since it's all facts, not advice.
Could look like this:
INFO: free space map contains N1 pages in N2
OK, new text is:
INFO: free space map contains 36 pages in 51 relations
DETAIL: A total of 816 page slots are in use (including overhead).
816 page slots are required to track all free space.
Current limits are: 18000 page slots, 1000 relations, using
11 matches
