I bet there must be someone more crazy

PostgreSQL

17 October 2024 07:33

yeah, I mean are there any disadvantages of being "too crazy"?

PostgreSQL

17 October 2024 07:19

“too crazy”
Are there any disadvantages?

Excel of all tools is not a reference for checking the sanity of a CSV...
I'm quite certain you'll have to adjust your quoting and/or delimiter settings (COPY expects tabs, Excel expects semicolons (in COMMA separated values, oh the irony))

PostgreSQL

16 October 2024 23:28

What copy command are you using?

PostgreSQL

16 October 2024 23:26

It means one of the rows has more columns than expected. Usually happens for example when you have unquoted text


For example this csv file:

id,sentence
1,Hello
2,I'm fine thanks
3,I like bananas, you?

PostgreSQL

16 October 2024 23:23

hello, please can anyone help?
I tried import csv file into my PostgreSQL 14 server and it is giving me error
ERROR: extra data after last expected column

PostgreSQL

16 October 2024 23:06

the problem is the join is based on the M-M relation, the index for the FK is there, but the date to sort it is in the B table

PostgreSQL

16 October 2024 23:05

Would have thought lateral would be the way to go. Is there an index on the column determining the 'first' row?

PostgreSQL

16 October 2024 23:02

Uh well, these days the optimizer will produce the same plan for a CTE and a classic JOIN anyway.

*Do* you have an index on that a_id column?

PostgreSQL

16 October 2024 22:59

the CTE is a current improvement, the 'in use' version doesn't have it, it's just a left join, I tried the lateral join and the query time increase

PostgreSQL

16 October 2024 22:55

well, he's certainly not going to be any less clueless after seeing your answer.

PostgreSQL

16 October 2024 22:54

But you are VP, Chief Database Scientist @ EnterpriseDB, PostgreSQL Major Contributor and Committer

PostgreSQL

Zero change of being adapted by anyone except us.
It is an disadvantage

PostgreSQL

17 October 2024 07:20

Yes, design is wrong. I know it for sure, it is designed by me

PostgreSQL

17 October 2024 07:16

Maybe pg_basebackup should have too. But wal-g design of this feature is too crazy for being adapted by pg community as-is

PostgreSQL

17 October 2024 06:51

dm I could help yeah

PostgreSQL

16 October 2024 23:35

Also, the encoding must be the same as of the database, and should include the first row as headers also in pgadmin

PostgreSQL

16 October 2024 23:32

You're using pgadmin?

PostgreSQL

16 October 2024 23:28

I opened it on excel, it looks so arranged

PostgreSQL

16 October 2024 23:26

the a_id column is in join table B only have date

PostgreSQL

16 October 2024 23:08

Maybe an index on B.date or composite of B.a_id, B.date might make the lateral approach fast.

PostgreSQL

16 October 2024 23:06

nope, how can I do that?

PostgreSQL

16 October 2024 23:04

Mind sharing the plan? On explain.dalibo.com for example?

PostgreSQL

16 October 2024 23:01

OP obviously was at the *very beginning* of his PG journey. As much as I'd *love* to give every newbie coming here a 4-day beginners course, *especially* on backup & recovery, as much do I not have the time to do so.

I do link my 50-min talk here on a regular basis (it seems), which I - to this day - conceive as a nice primer.

Let's just settle on that we won't overwhelm newbies with bold claims like "pg_dump is not a backup tool" in the future, eh?

PostgreSQL

16 October 2024 22:56

it's honestly shocking to me that we're having this discussion.

PostgreSQL

16 October 2024 22:54

Not clueless person @ his home, playing with postgresql (not understanding)

PostgreSQL

16 October 2024 22:53

i have used pg_dump -n many times and not once has it made my database unrecoverable.
