*

* 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
|
2010-12-15 20:11:31 +08:00
|
|
|
* we need to actually perform the upgrade, but it provides enough for
|
2010-05-12 10:19:11 +08:00
|
|
|
* check mode. We do not implement pg_resetxlog -n because it is hard to
|
|
|
|
* return valid xid data for a running server.
