Depends on what needs to be matched. The * matches the null string too,
so the two patterns * and *? are different (the latter requires at least one character):

Code:
$ cat s
case $pn.$db in
   *?.fcp?(db)  ) printf '%s in the first case\n' "$pn.$db matched" ;;
   *.fcp?(db)  ) printf '%s in the second case\n' "$pn.$db matched" ;;
esac

Code:
$ pn= db=fcp
$ . s
.fcp matched in the second case
$ pn=a db=fcp
$ . s
a.fcp matched in the first case
