Postgres data compress - postgresql

I am using Postgres ( 12.5 ver on ubuntu OS and it is community edition).
I am looking for columnstore features in postgres. While creating column store index it is giving me ERROR: access method "columnstore" does not exist.
Also i am looking for other option like default_table_access_method = zedstore; It is showing the error as listed below
ERROR: invalid value for parameter "default_table_access_method": "zedstore" DETAIL: Table access method "zedstore" does not exist.
Please can you help me to resolve this issue?

Trying to set constraint - new primary key in table, but getting an error: column "amgettuple" does not exist (pgadmin3)

I am creating a new table using pgadmin3 and when I click on constraints to add a primary key, I get this error:
I searched on google but I'm not finding this "amgettuple" issue. Does anyone know what this means? I am new to postgres and using pgadmin, just set it up an hour ago.
Postgres version: 9.6
pgadmin version: 1.22.2
linux mint 18
Install pgAdmin 4. pgAdmin III was supported up to 9,5 version I think.
I am also using pgAdmin 3 and got that error. I fixed it by using the Query Tool:
ALTER TABLE table_name
ADD primary key (column_name);

phraseto_tsquery in PostgreSQL 9.5x or just from 9.6x?

I'm finding references in the 9.5 manual to phraseto_tsquery
https://postgrespro.com/docs/postgrespro/9.5/textsearch-controls
But if I use it in my query it gives me this error:
No function matches the given name and argument types.
SELECT phraseto_tsquery('english', 'The Fat Rats');
Was this function not added with 9.5 as intended or is it likely there's some other problem on my side. Running 9.5.4 of the database currently. Anyone that can confirm?
For anyone looking; took the step to install postgresql 9.6beta4 and I'm no longer receiving the error message. In other words phraseto_tsquery seems to only be fully supporting in the current 9.6 beta and upcoming full release.

PhpStorm - ERROR: type "hstore" does not exist

I use primary pgAdmin to browse and edit my PostgreSQL database. Now I would like to use PhpStorm.
In PhpStorm I can browse my tables, but I can not edit data. When I try I get error:
[42704] ERROR: type "hstore" does not exist
Kde: compilation of PL/pgSQL function "on_update" near line 3
Function on_update is on update trigger and it save old row to history table and it uses hstore type.
PhpStorm uses postgresql-9.4-1201.jdbc4.jar driver. I don't know if it is driver error or PhpStorm error. I know that in pgAdmin it works and in PhpStorm not.
I work with same environment as Vojtěch and I have found that the extension is indeed created and present. But in different schema (public) then the current connection operates (the PostgreSQL search_path). There is probably bug in PhpStorm as its not respecting PostgreSQL user's default search_path.
Some workarounds (for DB console only):
In database console you use RESET SEARCH_PATH; statement.
You can enforce search_path on JDBC connection, see the question.

ODBC Call failure from Microsoft Access to PostgreSQL -Client Encoding Mismatch

i tried to create a linked table from Microsoft Access (2007) to PostgreSQL (9.0) in Windows 7. When I tried to linked table as follows:
1)Select link to the data source by creating a linked table
2)Machine Data Source in 'Selectr Data Source' pop up.
3)Select the PostgreSQL DB visible which ends in error:
ODBC call failed
Clientencoding mismatch(#214).
Could you please help?
I used Google to find this.
It seems that there is some problem with PostgreSQL 8.1 and the encoding names: see this post or google. It looks that UTF8 used by default with the new Postgres is not compatible with old ODBC drivers. I am not sure where the problem really is, but a quick fix is to change default encoding for the user connecting to the database:
alter user <user> SET client_encoding to LATIN1;

Postgresql error: could not open segment 1 of relation base/20983/2416

I'm running a Postgresql query and getting the following error:
ActiveRecord::StatementInvalid (PGError: ERROR: could not open segment 1 of relation base/20983/24161 (target block 5046584): No such file or directory
The query is of the format 'SELECT "locations".* FROM "locations" WHERE ("locations"."id" IN (115990, 78330, 77891, 78248, ...)' with about 600 ids in the IN clause - not an optimal query I know but it's what I have to work with for the moment!
The server is running PostgreSQL 8.4.6 on x86_64-pc-linux-gnu, compiled by GCC gcc-4.4.real (Ubuntu 4.4.1-4ubuntu9) 4.4.1, 64-bit. Postgis 1.5 is also installed, and the locations table contains a geometry column.
Anyone have any idea what could be causing the error? Thanks!
That error indicates serious database corruption, one of the database's files containing the table data (of something in the system catalogue?) is missing. I doubt you'll be able to do much beyond restoring the data from a backup.
