Understanding EXPLAIN ANALYZE estimates when loops != 1

[Philip Semanchuk <philip@xxxxxxxxxxxxxxxxxxxxx>]

Hi all,
I could use some help interpreting EXPLAIN ANALYZE output. 

->  Index Scan using ix_foo on t1 (cost=0.69..68.57 rows=3283 width=105) (actual time=0.006..0.918 rows=3760 loops=94)

The actual rows returned by this plan node ~= 3760 * 94 = 353,440. Did postgres expect (estimate) 3283 rows from this join, or 3283 * 94 = 308,602? 


Same question for this node.

->  Parallel Index Scan using pk_xyz on xyz  (cost=0.29..2354.67 rows=54285 width=25) (actual time=0.049..6.326 rows=14864 loops=5)

Actual rows ~= 14864 * 5 = 74,320, estimate = 54285 or 54285 * 5?


THanks
