Thanks, Benny.

In looking at the patch, I am guessing the main issue you fixed was that 
it will create an additional create index command, and that we do not 
want to send it down to the data nodes since one already ran as part of 
the create table.

I think we should try and avoid modifying the existing PostgreSQL 
function parameter list like that for transformIndexConstraints() if 
reasonably (stress: reasonably) possible to make merging and maintenance 
of PostgreSQL easier.  Can CreateStmtContext.isalter be used instead? 
Can it even be used in utility.c instead of isFromCreateStmt?

Thanks,

Mason

Benny,

Just to provide more background, PostgreSQL uses MVCC, so transaction 
ids (XID or GXID) are important for determining what is visible within 
the database.  These IDs are obtained from GTM. If in the cluster these 
advance and GTM is restarted with a low XID, then your previous work 
will not be visible. It is important to start it with at least the last id.

As Koichi mentioned, if you stop gracefully it will write the current 
value in a file and on restart will read this value (unless overridden 
by a passed in value).  If GTM crashed and you restart, you will need to 
manually pass in a high value. As Koichi also mentioned, we are 
currently working on this to recover this value properly.

Regards,

Mason

How did you stop and restart GTM?

If you stop gtm gracefully, it will restart to start with next GXID. 
If GTM crashed and you restart, you may need to specify GXID to start with.

Safer GTM recovery and restart will be implemented by the end of this year.

Deras,
 
When I restart the GTM, all my tables disppeare. I don't know why. Is is a problem or was what I did wrong? 
 
Your reply will be appreciated.
