Thread: create_immv issue on aws Ubuntu even after create extention

Hello all.

I am not able to use create_immv in postgresql 16.6 even after installing it and doing create extention.

I did a git clone of the repository and then make sudo make install to install it.

The issue is not happening on my local ubuntu 24.04 machine but on ubuntu 24.04 on aws free tier.

All dependencies are in place, that's why the extention got installed in the first place.

I get the error "function create_immv(unknown, unknown) does not exist.

all the tables related to this view exist, data is present and same setup works perfectly on my local machine, same OS and postgresql version.

Can someone suggest what could be the solution?

Regards.

Ok here you go.

select create_immv('plantskillpayment', 'select distinct kwapp_plant.id as plantid, kwapp_skill.id as skillid, kwapp_skill.skillname, kwapp_plant.plantname, kwapp_pltsklpaylvl.level, kwapp_pltsklpaylvl.pay from kwapp_skill, kwapp_plant,  kwapp_pltsklpaylvl  where kwapp_skill.id  = kwapp_pltsklpaylvl.skillid_id  and kwapp_plant.id = kwapp_pltsklpaylvl.plantid_id');

You see, the point is this works perfectly on all local machines with exact same versions and same data.

Regards.

What command did you run to get that error?

Differing search_path values can lead to problems like this.

In psql do:

\dx

That will show you what extensions are installed and in what schema.

Then read this:

https://www.postgresql.org/docs/current/ddl-schemas.html#DDL-SCHEMAS-PATH

It explains search_path and how to modify it.

Thank you.

Just a quick question.

should it be in pg_catalog?

if yes then it is so.

All done, but no result.

I feel it is possible that the latest code must be flawed or something.

Well, as a matter of fact, I never had to compile the extention on my local ubuntu 24.04 machine.

I just did a create extention and it worked just fine.

But on my aws server I had to compile it manually and still it does not work.

Regards.

When you know that the SELECT statement runs on the local machines, then on each server, run these SQL statements:

SHOW search_path;

SELECT * FROM pg_extension;

How did you install Postgres on the AWS EC2 instance?

Did you install the postgresql-server-dev-16 package?

create extension command works successfully.

But when I try creating the same immv on the server it says function create_immv (unknown, unknown ) does not exist.

Note that this works on my local machine.

Connect with psql then do:

1) \dx
This will show what extensions are installed and in what schema.

2) show search_path;

3) \df *.create_immv

Provide the outputs from the above three commands in your response.

So the extension functions are in the pgivm schema.

You will need to either always schema qualify the functions:

select pgivm.create_imv();

or  add the pgivm schema to the search_path.

For how to do that see the link I provided earlier in this thread:

https://www.postgresql.org/docs/current/ddl-schemas.html#DDL-SCHEMAS-PATH

Using the info from above you will probably want to persist the 
search_path setting in postgresql.conf as:

https://www.postgresql.org/docs/current/runtime-config-client.html

as

search_path

See this issue for why this is different now.

https://github.com/sraoss/pg_ivm/pull/116

Then deal with the fact it is no longer installed to pg_control but instead pgivm. With usual schema qualifications or search_path techniques.

Thank you david.

Can you tell me how exactly should the syntax be?

Is my function definition wrong?

Thank you, it worked.  now pgivm.create_immv works.

I should have got it before.

Actually I depend on a screen reader given my total blindness.  Somehow it is playing some tricks with thunderbird these days.

Some times when there are multiple nested blocks, I may miss the text.

But any ways thank you very much.

I had doubted it on similar lines, but could not pinpoint the issue.

Yes perfect thank you.

Besides, I will soon switch over to Mac air m3 and voice over does not have such problems.

This screen reader Orca is great as well and I am very sure, that it being open source, will have the issue fixed at the earliest.
