[SQL] pg_restore error - Any Idea?

[DM]

Hi All,

I am facing an error on executing the below command

dump name: pg_dump_FcZ0.pnps_200903041201_1.2.1.0_base_testing
databae name: pnqd_test

$pg_restore -U postgres -p 5433 -d pnqd_test
pg_dump_FcZ0.pnps_200903041201_1.2.1.0_base_testing

pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 3715; 0 0 ACL monitor
postgres
WARNING: errors ignored on restore: 1

I am not able to figure out this issue. Any idea guys.

Thanks

Hi All,

I have a database of 10GB.
My Database Server has a RAM of 16GB

Is there a way that I can load all the database objects to memory?

Thanks for your time and taking a look at this question.

[SQL] how to set the value to the column

[DM]

Hi All,

I have a table test with columns name and value

test table
name
value

It has around 500 rows.

I added a new column id to the table,

Table test
id,
name,
value

I am not sure how to insert numbers to my column id (1-500).

Thanks
