I have some questions below:<br />(1) Query with `Seq Scan`<br />(2) Query with `Index Scan`<br />- How do you know the query (2) is faster (or as "more effective" in the post) than query (1)? Because the number of rows output and rows' width are the same, but the cost in query(2) is much higher than query(1)<br />- Do you have a version with `EXPLAIN ANALYZE` as it would have the execution time?<br />- And did you VACUUM ANALYZE the table before explain query since it would make help update the table statistics (also clean up the index tree), hence the planner would make right decision.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-308191087296040302.post-70552789243347783572019-04-16T13:37:12.411+07:002019-04-16T13:37:12.411+07:00I was on Postgres 10.6

First owners would have to give up individual ownership for a collective one (think of hợp tác xã for a legal entity equivalent), then they would have to commission a construction company to perform safety review and all sorts of maintenance task (and pay for these themselves), only until then can they legally lease their slots to businesses.<br /><br />Giving it another thought, this sounds just as much as turning your "small private guy" into a "big private guy".Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-308191087296040302.post-20604349698843067992016-03-07T06:12:08.585+07:002016-03-07T06:12:08.585+07:00I think unconventional interview questions work ju...I think unconventional interview questions work just as well as an unconventional <a href="http://www.interviewshack.com/2016/03/03/ten-powerful-ways-to-improve-your-resume/" rel="nofollow">resume</a> does - that is, they don't work at all.
