Обсуждение: Steps to Install archived Postgres 9.3 and 9.6

Are you really sure that your application software (Jira) is incompatible with current PostgreSQL versions?

Please make a test whether it works. It might very well do.

In most cases, not only the approved PostgreSQL versions work fine with application software, but also all younger versions.

Backward compatibility is very high.

Holger

Thanks all. This really helps. Will let you know if any issues.

Hi,

We have a requirement where we need to migrate Oracle to Postgres. However the current version of Application JIRA is 6 and it is not compatible with Postgres 11. We need to do an incremental upgrade like below.

1. Migrate Oracle 11g to Postgres 9.3.

2. Upgrade JIRA 6 to 7.

3. Upgrade Postgres 9.3 to 9.6.

4. Upgrade JIRA 7 to 7.x

5. Upgarde Postgres 9.6 to 11.

6. Upgrade JIRA 7.x to 8.x

Does anyone have steps to install PG 9.3 and 9.6. I know it is not supported anymore but we are stuck with this approach. Please help :(

Regards,

Aditya.

Good Morning & Good Evening All,

 As Migration, I need to convert one table from Oracle (Source) to Postgres(Target)

The Oracle Table is created as below: 

The oracle table is external table. What is external table : We will keep  files(CSV/ flat files) in drive, we will create a one physical table in oracle and when we select * from table, The oracle external table will go to the CSV/Flat file and it will pull the data from the table and will share results to the user. 

FYI : it won’t store any physical data in the oracle database.

Requirement : we need similar kind of external concept in POSTGRESQL RDS. The data ( CSV/Flat) is storing in S3 Bucket.

Could some one share doc/ URL .

Thxs,

Deva

Well, the same feature in Postgres is called file_fdw. The documentation is here: https://www.postgresql.org/docs/14/file-fdw.html

Here is an example: https://dbaclass.com/article/how-to-access-csv-files-on-file-system-using-file_fdw_in_postgres/

Good luck!

PS:

I hate foreign tables in Oracle and I don't use them in Postgres. You cannot index them and about the only thing you can do with them is sequential scan. The problem with that is that the larger file gets, the more time it takes to process it. External tables in Oracle were meant as a shortcut for loading them, bypassing SQL*Loader. You are the first person in my 30 years long career of an Oracle architect/DBA/consultant who uses external tables.

Thanks Mladen,

Getting this error, when tried to create extension in AWS RDS .

If you are going to use RDS, you will be limited to what Amazon provides--meaning you will have to load the data into a
table:

Then do yourself and your users a favor and upgrade to a recent
release of JIRA, which supports at least PostgreSQL v13.
