postgresql 9.6 – Physical and logical replication slots in Postgres (at the same time)

I wonder if it is possible to have a configuration when changes from a single Postgres master are transmitted to two (or more) replicas at the same time, but do some replicas to use transmission replication (logic) and some to use physical replication? ?

So far I've only seen examples of how to use one of those, but not both at the same time.

I am currently in Postgres 9.6, but I could update it, if necessary.

Thank you!

postgresql – In Postgres 9.6, why is the GIN index not used for a JSONB column with text / int array?

In Postgres 9.6, why is not the GIN index used in my next SELECT query for a JSONB column with text / int array? How do I force the GIN index to postgres?

SET enable_seqscan to FALSE;

EXPLAIN ANALYZE SELECT * FROM WHERE int_array_cast (metadata - >> & # 39; types & # 39;) @> & # 39; {52, 53} & # 39;


Seq Scan in articles (cost = 10000000000.00..10000000016.07 rows = 1 width = 2391) (real time = 0.073..0.117 rows = 1 loops = 1)
Filter: (int_array_cast ((metadata - >> & # 39; types & # 39; :: text)) @> & # 39; {10,14} & # 39; :: whole[])
Rows eliminated by the filter: 37
Planning time: 0.201 ms
Run time: 0.197 ms

Structure of the table

CREATE TABLE "articles" (
"item_uuid" UUid NOT NULL,
"metadata" JSONB,
PRIMARY KEY ("item_uuid")

int_array_cast definition of functions


Index created using GIN

CREATE INDEX IF THERE DOES NOT EXIST items_metadata_dok_index ON elements that use GIN (int_array_cast (metadata - >> & # 39; types & # 39;))

Sample elements in the table.

item_uuid | metadata

                1 | {"types": "{1,2}", "name": "item_name1"}
2 | {"types": "{10,11}", "name": "item_name2"}
3 | {"types": "12", "name": "item_name3"}
3 | {"name": "item_name4"}

postgresql 9.6 – Why does tsrange (& # 39; 2018-01-01 & # 39 ;, NULL) @> transaction.transacted_at use the b-tree index?


Create table transactions
transacted_at TIMESTAMP

CREATE INDEX IF THERE IS NO EXIST_transactions_on_transacted_at
Transactions ON (transacted_at);

Then this does not use the index:

SELECT * OF transactions
WHERE tsrange (& # 39; 2018-01-01 & # 39 ;, NULL) @> transacted_at;

But this does:

SELECT * OF transactions
WHERE transacted_at> & # 39; 2018-02-01 & # 39;

I realize that I can simply deconstruct the range and make the comparison work, but I would like to know how I can use the ranges natively with an index in the transaction table.

What am I missing?

Windows Application – JoeAlter Shave and a haircut for Maya 2016-2018 9.6 v15 | NulledTeam UnderGround

File size: 31.7 MB

Joe Alter Shave and a Haircut is a complement for Maya, which creates more realistic hair and coat surfaces. With this, you can create furry animals, pastures, haircuts, mustaches, etc. And this is not only an extra realistic skin / hair, but also an additional realistic and dynamic one. By combining the advantages of the Maya Fur and Maya Hair modules within itself, JA S & H is a perfect decision for its production. It facilitates the creation of haircuts with a much more precise level of control and much less time of reproduction. S & H is also compatible with MentalRay and RenderMan, so you can create super-photorealistic representations using no additional composition.

postgresql 9.6 – what is replay_lsn in postgres statistics replication

We are trying to implement Postgres transmission replication for which I am reading the PostgreSQL transmission replication material.

So far things look good, but I'm confused about what it is replay_lsn pointer meaning

At the beginning, I assumed that the playback position is updated when the process of the primary server control point is performed. but the replay_lsn value is something that is part of the STAND server.

which is what has puzzled me, so if someone can explain me in a simple term, it would be very useful.

The PostgreSQL database was lost after the update from 9.3 to 9.6

After upgrading a PostgreSQL 9.3 server to version 9.6, I discovered that some references were lost during pg_upgrade. Both servers are now running on the same machine

In the old database server I have two dbA and dbB databases, the problem is that after running pg_upgrade some data is missing in the dbB tables and all the data in the dbA tables are not there, only the schema. fortunately I kept cluster 9.3 and when I run queries from that cluster, all data is there as expected.
After checking some settings, I noticed that the dbA was in another table space.

There is a way to point Cluster 9.6 to 9.3 cluster tablespace and data dir?
When I did pg_upgrade I also copied the configuration files (the reason to load the schema and some data into a new cluster)

I do not have space to do a pg_dump / pg_restore. I also tried something more direct like

/usr/pgsql-9.3/bin/pg_dump -p 5433 dbA | psql -p 5432 dbA

But I ran out of space and when I checked the size of the databases I noticed a big difference, like 40 GB to 15 GB, so I think the command is ending with an error because there is no space left.

it's possible point to an existing database file location and upload to a new cluster?

Thanks in advance!!
