- * get_control_data()
- *
- * gets pg_control information in "ctrl". Assumes that bindir and
- * datadir are valid absolute paths to postgresql bin and pgdata
- * directories respectively *and* pg_resetxlog is version compatible
- * with datadir. The main purpose of this function is to get pg_control
- * data in a version independent manner.
- *
- * The approach taken here is to invoke pg_resetxlog with -n option
- * and then pipe its output. With little string parsing we get the
- * pg_control data. pg_resetxlog cannot be run while the server is running
- * so we use pg_controldata; pg_controldata doesn't provide all the fields
- * we need to actually perform the upgrade, but it provides enough for
- * check mode. We do not implement pg_resetxlog -n because it is hard to
- * return valid xid data for a running server.
