Dear PostgresSQL Hackers, I am working in optimizer module of postgreSQL 9.4.1. I am trying to return a subplan for a query instead of full plan. For this I need to return an intermediate plan (or path) from the DP lattice (i.e. from *RelOptInfo *standard_join_search() *at* allpaths.c) *instead of the full optimal plan (which is from the last level of *root->join_rel_level()).* while doing so I am getting *error :variable not found in subplan target lists* at function *fix_join_expr_mutator* at *setrefs.c.*
It will be great if you can give me some idea about why this error is happening, since this error is happening at *fix_join_expr_mutator* function at *setrefs.c.* Please give me more information about this portion of code. Also I would like to know for what targetlist stands for. Thanks, Srinivas Karthik
