Well, it's ugly (I don't like non-reentrant library routines), it's
not really buying anything, and I don't think you've got the corner
cases right anyway.  I'd go for something like

    if (strlen(adsrc) > 19 &&
        strncmp(adsrc, "nextval('\"", 10) == 0 &&
        strcmp(adsrc + strlen(adsrc) - 9, "\"'::text)") == 0)

            regards, tom lane
