Well, it is simple.
As we wrote, some of us think that cursors are useful, and we tried to
explain why we think that. If you don't think that cursors are useful,
don't use them. We are not out to convince you otherwise.

Hey Daniel,
Thanks for getting back to me.
I think the issue I'm having is that my build of Postgres is missing uuid
pieces needed by our users.
They're executing the command: CREATE EXTENSION "uuid-ossp"
and getting the error
ERROR: could not open extension control file
Environment: PostGres 13 on RedHat 7.9.
I am using logical replication (publisher/subscriber) between two databases and
there are times where one of our schemas gets to 100% of allocated space (No
Free Extents). I went into the schema and did a \dt+ to see the amount of
size being used and I

Ouch. In fact, I had read the whole of the "43.7. Cursors" section in the
"PL/pgSQL" chapter (www.postgresql.org/docs/15/plpgsql-cursors.html). And

What's strange is that there is only 1 non-unique value in the column.

I've downloaded the PostgreSQL 14.7 source and building it on Windows 64bit and

I'm using the Visual Studio tools in the src/tools/msvc folder.
I'm trying to build with the uuid extension but it looks like I need uuid-ossp
installed in order
to get it to work.

Hey,

This came up on Reddit [1] the other day and boils down to the question:

That worked, thanks. I was trying to find how to do that in pgsql.

So the problem is that awful rowcount

Stop the server, start it in single-user mode (postgres --single),
issue an ALTER USER command to undo the damage.
Or modify

What does the EXPLAIN look like with seqscans disabled?

Yes, I forgot to mention I did a REINDEX DATABASE and ANALYZE.

Can i create a brand new cluster and check it that way? Since I had to stop /
shut down the 14 cluster in order to proceed with pg_upgrade and I dont know
how can i connect to it now ...

Did you run ANALYZE on the database/table in the new 15.2

Hi,
I want to remove not needed decimal places / trailing zeros from a numeric.
I know this can be done starting PG >=13 with TRIM_SCALE(numeric) which would
solve my issue (with an additional CAST to TEXT at the end).
Unfortunately the production database is still running with PostgreSQL 12.x

Sure, create a new cluster in *same way* you will

The check in question performs this:
SELECT COUNT(*) FROM pg_catalog.pg_roles WHERE rolname !~ '^pg_';
What do you get when running that in the new v14 cluster?

Hello, Im trying to upgrage the db version to a newer one with the command:
'/usr/lib/postgresql/14/bin/pg_upgrade --old-bindir /usr/lib/postgresql/9.6/bin
--new-bindir /usr/lib/postgresql/14/bin --old-datadir /etc/postgresql/9.6/main
--new-datadir /var/lib/postgresql/14/data -U postgres'
See noddy example below (v14.6).
Presumably this is a result of procedure cacheing as per docs. The EXECUTE
plan is being prepared fresh (again as expected from the docs and per the error
message) but is the input argument type of NEW.x for the format() call still
cached? Is altering a table
