Patch applies cleanly, compiles, works for me.

I meant the added one about -I, not the pre-existing one about -i.

I would like to insist a little bit: the name was declared as an int but
passed to init and used as a bool there before the patch. Conceptually
what is meant is really a bool, and I see no added value bar saving a few
strokes to have an int. ISTM that recent pgbench changes have started
turning old int-for-bool habits into using bool when bool is meant.
initialize_cmds initialization: rather use pg_strdup instead of
-I: pg_free before pg_strdup to avoid a small memory leak?
I'm not sure I would have bothered with sizeof(char), but why not!
I'm still a little bit annoyed by checkCustomCmds: when unhappy, it shows
an error message and return false, which immediatly results in exit(1).
However the pattern elsewhere in pgbench is to show the error and exit
immediatly. I would suggest to simplify by void-ing the function and
exiting instead of returning false.
