ah ok FC thus means FontConfig.

On my system I also have a 9.21 gs, (a Fink installed one)

$ /sw/bin/gs --help
GPL Ghostscript 9.21 (2017-03-16)
Copyright (C) 2017 Artifex Software, Inc.  All rights reserved.
....
Ghostscript is also using fontconfig to search for font files
For more information, see /sw/share/ghostscript/9.21/doc/Use.htm.
Please report bugs to bugs.ghostscript.com.

which uses fontconfig

$ which -a fc-list
/opt/local/bin/fc-list
/sw/bin/fc-list
/opt/X11/bin/fc-list

but its ps2pdf does not report a FC_WEIGHT problem.

I got the "problem" with Ghostscript 9.23 and TeXLive 2018 and now with
Ghostscript 9.26 (in conjunction with TeXLive 2018, and with TeXLive 2019 pretest)
which got installed on my Mac OS via MacPorts.

However I do not seem to have any fontconfig generated database files in my $HOME.

I presume MacTeX distribution of TeXLive comes with own Ghostscript build
and will not display the issue ?
