It's easier to review rendered documentation.
I made a rendered copy available here:
https://api.cirrus-ci.com/v1/artifact/task/6084297781149696/html_docs/html_docs/install-meson.html

+ <application>Flex</application> and <application>Bison</application>
+ are needed to build <productname>PostgreSQL</productname> using
+ <application>meson</application>. Be sure to get
+ <application>Flex</application> 2.5.31 or later and
+ <application>Bison</application> 1.875 or later from your package manager.
+ Other <application>lex</application> and <application>yacc</application>
+ programs cannot be used.

These versions need to be updated, see also: 57bab3330:
- b086a47a270 "Bump minimum version of Bison to 2.3"
- 8b878bffa8d "Bump minimum version of Flex to 2.5.35"

+ will be enabled automatically if the required packages are found.

should refer to files/libraries/headers/dependencies rather than
"packages" ?

+ default is false that is to use <application>Readline</application>.

"that is to use" should be parenthesized or separate with commas, like
| default is false, that is to use <application>Readline</application>.

zlib is mentioned twice, the first being "strongly recommended".
Is that intended? Also, basebackup can use zlib, too.

+ If you have the binaries for certain by programs required to build

remove "by" ?

+ Postgres (with or without optional flags) stored at non-standard

Actually, I suggest to say:

.. with different values ..

Maybe other things should have <productname> ?

Git
Libxml2
libxslt
visual studio
DTrace
ninja

+ <application>Flex</application> and <application>Bison</application>

Maybe these should use <productname> ?

Should be <application> ?

This part is redundant with prior text:
" To use this option, you will need an implementation of the Gettext API. "

+ Enabls use of the Zlib library

typo: Enabls

Maybe say the "code" is not optimized ?

+ To learn more about running the tests and how to interpret the results

interpret the results comma
"for interpreting test results" seems redundant.

+ ninja install should work for most cases but if you'd like to use more options

cases comma

Starting with "Developer Options", this intermixes postgres
project-specific options like cassert and tap-tests with meson's stuff
like buildtype and werror. IMO there's too much detail about meson's
options, which I think is better left to that project's own
documentation, and postgres docs should include only a brief mention and
a reference to their docs.

+ Ninja will automatically detect the number of CPUs in your computer and
+ parallelize itself accordingly. You can override the amount of parallel
+ processes used with the command line argument -j.

too much detail for my taste..
