Help with restoring database from old version of PostgreSQL

PostgreSQL/PostGIS installation, but when I try to connect to the

SELECT postgis_version();
I get the following error message: ERROR: could not open extension

No such file or directory SQL state: 58P01

How can I restore my database to have access to it again?

Do you still have the backup file somewhere? If so, then modern versions
of PG *will* read the 9.6 backup file. You "just" need to have PostGIS
somewhere on disk that PG 16.3 knows about.

Yes, I still have the backup file. I tried to open pgAdmin4 today to see
what version I'm running, and now this happened (see attachments). My
operating system is Windows 10 Home, version 10.0.19045 Build 19045. I
installed Postgres using these instructions:
https://basille.org/postgis2017/installation_instructions/install_postgresql.html
I'm
guessing at this point I probably need to start all over with the
installation since pgAdmin4 is not working? But if 9.6 is no longer
supported, can I still use it to access my database? I assumed I would need
to migrate to the most recent version of PostgreSQL, but maybe that was a
wrong assumption?

Thank you for your help,

1. PG16 will read a PG 9.6 backup file, so there's no need to install PG
9.6.
2. Installing PG on a OneDrive share is certainly a Very Bad Idea.
3. PG is not the same as PgAdmin.

1) You can copy/paste the error message and provide as text.

2) Assuming you are installing Postgres 16 from the EDB package, the
from here:

https://www.postgresql.org/download/windows/

PostgreSQL Version 64 Bit Windows Platforms
16 2022, 2019

[...]
11 2019, 2016, 2012 R2
10 2016, 2012 R2 & R1, 7, 8, 10

3) From here:

https://www.enterprisedb.com/downloads/postgres-postgresql-downloads

9.6 can still be downloaded.

It is not a supported version, but you can at least use it to access
your database.

4) You need to provide a more detailed explanation of what you are
trying to achieve.

5) 9.6 -> 16 is six major version jump. That means some research needs
to be done, starting with determining what version of PostGIS you need
to be using.

I am trying to restore a previously backed up database .sql file that was
created in PostgreSQL 9.6 using pgAdmin4 (I'm not sure which version I was
using).

In response to Ron: Do I need to use PG16 instead of pgAdmin4? And if so,
can you please provide a website where I can download PG16?

In response to Adrian: How do I determine what version of PostGIS I need to
be using? When I installed it, I was only given one option of a version to
install.

Since my previous installation of pgAdmin4 was not working, I have started
over today, uninstalling all versions of PostgreSQL that I had and
reinstalling PostgreSQL Version 17.0 from https://www.enterprisedb.com/ and
pgAdmin4 version 8.12 from https://www.pgadmin.org. I tried installing
PostgreSQL 9.6.24 also, but I received an error message when I run the
installation file: "An error occurred executing the Microsoft VC++ runtime
installer." I installed the latest versions of the PostGIS (3.5.0) and
psqlODBC drivers (I'm forgot to write that down and am not sure how to
check the version). My installation of PostgreSQL/PostGIS was verified as
successful. I am able to connect to the PostgreSQL 9.6 and 17 servers. I
set the PostgreSQL Binary Path to: C:\Program Files\PostgreSQL\17\bin. I
have tried to restore my database using this in the command prompt: "psql.exe
db_2024_9 < C:\postgis\db_2017-08-16.sql postgres" using an empty database
in both the PostgreSQL 9.6 and 17 servers, and this is the result:

Ah, so it's a plain old SQL file. That makes things much easier!!

Here's the thing: PG (whether 9.6 or 16 or 17) is the database engine; no
GUI, and just a basic command line interface.
PgAdmin4 is a GUI interface to PG. Newer versions of PgAdmin4 are not
compatible with EOL PG versions like 9.6.

What you need is *both* a new PG version *and* a new PgAdmin4 version.

*Then* you need to:
CREATE USER basic_user WITH PASSWORD 'random_horse';

After that, you can run the "backup sql script".

Go here:

https://postgis.net/development/source_code/

and look in the release notes. They will tell you what range of Postgres
versions are supported. For instance the latest 3.5.0:

https://git.osgeo.org/gitea/postgis/postgis/raw/tag/3.5.0/NEWS

"To take advantage of all postgis_sfcgal extension features SFCGAL 1.5+
is needed. PostgreSQL 12-17 required. GEOS 3.8+ required. Proj 6.1+
required. "

Since my previous installation of pgAdmin4 was not working, I have
started over today, uninstalling all versions of PostgreSQL that I had
and reinstalling PostgreSQL Version 17.0 from
https://www.enterprisedb.com/ <https://www.enterprisedb.com/&gt; and
pgAdmin4 version 8.12 from https://www.pgadmin.org
<https://www.pgadmin.org&gt;. I tried installing PostgreSQL 9.6.24 also,
but I received an error message when I run the installation file: "An

"psql.exe db_2024_9 < C:\postgis\db_2017-08-16.sql postgres" using an
empty database in both the PostgreSQL 9.6 and 17 servers, and this is
the result:

1) Is db_2017 a database you had on old server?

2) What backup did you do in pgAdmin4 for the 9.6 instance?

Did you do the entire server:

https://www.pgadmin.org/docs/pgadmin4/8.13/backup_server_dialog.html

or backup just one database?:

https://www.pgadmin.org/docs/pgadmin4/8.13/backup_dialog.html

If the latter then you did not get the global objects for the Postgres
9.6 instance. This includes roles(users) and would account for the user
errors.

To get the global objects use:

https://www.pgadmin.org/docs/pgadmin4/8.13/backup_globals_dialog.html

     What OS and version are you running?

     How did you install Postgres?

You say that you just installed PG17. That's perfectly fine. If pgAdmin4
version 8.12 is recent, then it's fine to use that, too.

The thing is that sql files are just... a bunch of SQL statements.
Whatever SQL is generated by v9.6 will be easily processed by a modern
version.

Ah, so it's a plain old SQL file. That makes things much easier!!

Here's the thing: PG (whether 9.6 or 16 or 17) is the database engine; no
GUI, and just a basic command line interface.
PgAdmin4 is a GUI interface to PG. Newer versions of PgAdmin4 are not
compatible with EOL PG versions like 9.6.

What you need is *both* a new PG version *and* a new PgAdmin4 version.

*Then* you need to:
CREATE USER basic_user WITH PASSWORD 'random_horse';

After that, you can run the "backup sql script".

In response to Ron: Do I need to use PG16 instead of pgAdmin4? And if
so, can you please provide a website where I can download PG16?

In response to Adrian: How do I determine what version of PostGIS I need
to be using? When I installed it, I was only given one option of a version
to install.

Since my previous installation of pgAdmin4 was not working, I have
started over today, uninstalling all versions of PostgreSQL that I had and
reinstalling PostgreSQL Version 17.0 from https://www.enterprisedb.com/ and
pgAdmin4 version 8.12 from https://www.pgadmin.org. I tried installing
PostgreSQL 9.6.24 also, but I received an error message when I run the
installation file: "An error occurred executing the Microsoft VC++ runtime
installer." I installed the latest versions of the PostGIS (3.5.0) and
psqlODBC drivers (I'm forgot to write that down and am not sure how to
check the version). My installation of PostgreSQL/PostGIS was verified
as successful. I am able to connect to the PostgreSQL 9.6 and 17 servers. I
set the PostgreSQL Binary Path to: C:\Program Files\PostgreSQL\17\bin.
I have tried to restore my database using this in the command prompt: "psql.exe
db_2024_9 < C:\postgis\db_2017-08-16.sql postgres" using an empty database
in both the PostgreSQL 9.6 and 17 servers, and this is the result:

You need to take a step back and take stock of where you started and
where you want to be.

To that end answer the following:

1) What are the Postgres and PostGIS versions you started with?

2) What database or databases do you want to move forward?

3) Is there a hard requirement for what currently supported version of
Postgres you want to use?

4) What do you want to do with the new install?

5) What versions of Postgres, pgAdmin4 and PostGIS do you currently have
installed?

6) You are looking at jumping a minimum of 4 major Postgres versions up
to a maximum of 8 versions. You are also jumping some number of PostGIS
versions as well. In either case you should at some point go over the
release notes for each major version jump to see if anything is going to
cause issues.

Adrian: Yes, db_2017 is the name I originally gave the database in the
PostgreSQL 9.6 server. I can't remember if I used pg_dump or pg_dumpall.

Ron: Okay, I think it finally worked!

Thank you both for your help.

As Ron already pointed out, these are different things. PostgreSQL is a
Database. PgAdmin ist a Client for that database. You can't use one
instead of the other. You can only use them together (but of course you
could use a different client instead of PgAdmin4).

I set the PostgreSQL Binary Path to: C:\Program
Files\PostgreSQL\17\bin. I have tried to restore my database using
this in the command prompt: "psql.exe db_2024_9 <
C:\postgis\db_2017-08-16.sql postgres" using an empty database in both
the PostgreSQL 9.6 and 17 servers, and this is the result:

Password for user postgres:

[...]

ALTER DEFAULT PRIVILEGES
ERROR:  role "basic_user" does not exist

That looks fine except that the user "basic_user" doesn't exist. You
should create that before restoring the backup. Or could fix the errors
after the fact but for that you need to understand what went wrong.
