Hi Alvaro,
Please see few comments below:
1. Makecheck fails currently as view definition of expected rules.out does
not reflect latest changes in progress metrics numbering.
2. + <entry>
+ When creating an index on a partitioned, this column is set to the
+ total number of partitions on which the index is to be created.
+ </entry>
+ </row>
+ <row>
+ <entry><structfield>partitions_done</structfield></entry>
+ <entry><type>bigint</type></entry>
+ <entry>
+ When creating an index on a partitioned, this column is set to the
I think there is a typo here 's/partitioned/partitioned table/'
3.
+ if (hscan->rs_base.rs_parallel != NULL)
+ {
+ ParallelBlockTableScanDesc bpscan;
+
+ bpscan = (ParallelBlockTableScanDesc)
hscan->rs_base.rs_parallel;
+ startblock = bpscan->phs_startblock;
+ }
+ else
+ startblock = hscan->rs_startblock;
+
+ /*
+ * Might have wrapped around the end of the relation, if startblock
was
+ * not zero.
+ */
+ if (hscan->rs_cblock > startblock)
+ blocks_done = hscan->rs_cblock - startblock;
+ else
+ blocks_done = hscan->rs_nblocks - startblock +
+ hscan->rs_cblock;
+
+ return blocks_done;
I think parallel scan equivalent bpscan->phs_nblocks along with
hscan->rs_nblocks should be used similar to startblock computation above.
Thank you,
