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_option
xo("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 level for 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 ...
