Thanks for the suggestion, Michael.

Attached v2 with two patches:

0001 - Adds check_io_worker_gucs() with parameterized GUC names (%s)
0002 - Adjusts check_av_worker_gucs() to use the same format

Both now produce the same translatable errmsg pattern:
"\"%s\" (%d) should be less than or equal to \"%s\" (%d)"

Thanks,
