why there is _outInsertStmt() exists in outfuncs.c in pgpool 4.3.0

hi hackers,
I have a question, pgpool 4.3.0 , its parser based on PG14, so I think file outfuncs.c was got from PG14, is that right?

But I noticed that in PG14 , there is no _outInsertStmt() function in outfuncs.c , do you know why _outInsertStmt() existed in outfuncs.c of pgpool 4.3.0?

Thanks

No.

It was implemented in the initial release of Pgpool-II (in 2006). At that time Pgpool-II had a distribute database feature, which required rewriting INSERT queries. For the purpose outInsertStmt() was implemented.
