Hello All I'm researching on Index-Advisor Tools to be applied in SQL
queries. At first I found this: - EnterpriseDB -
https://www.enterprisedb.com/docs/en/9.5/asguide/EDB_Postgres_Advanced_Server_Guide.1.56.html
Someone would know of other tools for this purpose. I'd appreciate it if
you can help

where c.oid = l.relation

Now, I'm waiting to finish creating the index.

Hello all,
My scenario is: postgresql 10, Processor Xeon 2.8GHz / 4-core- 8gb Ram, OS
Debian 8.
When creating index on table of approximately 10GB of data, the DBMS hangs
(I think), because even after waiting 10 hours there was no return of the
command. It happened by creating Hash indexes and B

Hello All
I am using Postgresql extension pageinspect.
Could someone tell me the meaning of these columns: magic, version, root,
level, fastroot, fastlevel of the bt_metap function.
This information is not presents in the documentation.
The height of the b-tree (position of node farthest from r
, referring to the
height of the index tree?

Dear,
I'm trying to interpret an Explain Analyze, but I did not understand this:
-> According to the Postgresql documentation at: https://www.postgresql.org/
docs/9.6/static/using-explain.html
" the loops value reports the total number of executions of the node, and

Dear all
Someone help me analyze the execution plans below, is the query 12 of
TPC-H benchmark [1].
I need to find out why the query without index runs faster (7 times)
than with index, although the costs are smaller (see table).
I have other cases that happened in the same situation. The server
