Both the first run and subsequent run takes same amount of time.

*First Run:*

"Seq Scan on d_payer (cost=0.00..8610.40 rows=121788 width=133) (actual
time=8.760..98.582 rows=121788 loops=1)"
" *Buffers: shared read=2521*"
"Planning time: 16.820 ms"
"Execution time: 108.626 ms"


*Second Run:*

"Seq Scan on d_payer (cost=0.00..8610.40 rows=121788 width=133) (actual
time=0.010..18.456 rows=121788 loops=1)"
" *Buffers: shared hit=2521*"
"Planning time: 0.083 ms"
"Execution time: 27.288 ms"


Can anyone please help me understand and fix this.


Thanks & Regards,
Sumeet Shukla
