Just another way to do it:

#if defined(HAVE_GETOPT_LONG)
#define PARMPREFIX '='
#else
#define PARMPREFIX ' '
#endif

static void
explain_option(char *shortform, char *longform, char *parm, char *desc)
{int pos = 0;
printf("  -%s", shortform);pos += 3 + strlen(shortform);

#if defined(HAVE_GETOPT_LONG)printf(", --%s", longform);pos += 4 + strlen(longform);
#endif
if (parm) {    printf("%c%s", PARMPREFIX, parm);    pos += 1 + strlen(parm);}/*if*/
printf("%*c", 27 - pos, ' ');printf("%s\n", desc);
}/*explain_option*/

#define xo explain_optionxo("f", "file", "FILENAME", "output file name");xo("F", "format", "c|t|p", "output file format
(custom,tar, plain text)");xo("i", "ignore-version", NULL, "proceed even when server version mismatches\n"     "
                  pg_dump version");xo("v", "verbose", NULL, "verbose mode");xo("Z", "compress", "0-9", "compression
levelfor compressed formats");
 

This is only a quick hack, I didn't care for _() and
explain_option() could be smarter about multi line descriptions,
but you get the idea ...
