Let me see if I can fix that.
At long last, here is a patch.
If somebody has an idea how to code some of that less confusingly, let me know.
It is little bit hard to read.
/* If stage is -1, then run all stages. Otherwise, we got a stage * from vacuum_all_databases(), so just run that one. */ for (i = (stage == -1 ? 0 : stage); i < (stage == -1 ? 3 : stage + 1); i++) { puts(gettext(stage_messages[i])); executeCommand(conn, stage_commands[i], progname, echo); run_vacuum_command(conn, sql.data, echo, dbname, table, progname); }
maybe better be more verbose - and it can be in alone function, because it is "analyze only"
if (stage == -1)
{
for (i = 0; i < 3; i++) { puts(gettext(stage_messages[i])); executeCommand(conn, stage_commands[i], progname, echo); run_vacuum_command(conn, sql.data, echo, dbname, table, progname); } }
