In POSIX, -g and -u are mutually exclusive.  Solaris ignores all but the first
of these in a command:

[nm@gcc-solaris11 5:0 2021-07-01T06:48:54 postgresql 1]$ /usr/bin/nm -u -g src/interfaces/libpq/libpq.so|grep exec
nm: -u or -e set, -g ignored
[nm@gcc-solaris11 5:0 2021-07-01T06:49:41 postgresql 1]$ /usr/bin/nm -g -u src/interfaces/libpq/libpq.so|grep exec
nm: -e or -g set, -u ignored
