I get the following warning when I compile src/bin/pg_id/pg_id.c:

bmomjian · bmomjian · commit 329a1b72700e · 2003-08-09T01:25:46.000Z
gcc -pipe -g -Wall -Wmissing-prototypes -Wmissing-declarations
-I../../../src/include   -c -o pg_id.o pg_id.c -MMD
pg_id.c: In function `main':
pg_id.c:35: warning: unused variable `optarg'

The attached trivial patch fixes the warning by removing the variable.
