Re: How to add function schema in search_path in option definitio

[Lorusso Domenico <domenico.l76@xxxxxxxxx>]

eh.. yes to be honest what I create is more similar to an extension rather than a package, I don't believe to be able to create extensions in cloud sql (the actual target db).

However , is there a way to share this preliminar "extension" with the community?
I'm interested to discuss about solution used

For example: the software creates a custom type to manage bitemporality and audit_record inline for each table; but another approach is to use a primitive table inherited by all tables.

I'm quite sure the composite type has one or two fields I can remove.

etc :-D

Hello Adrian,

I've created a schema to handle some specific features.

In the schema there are a couple of tables used by many functions (more than 20).

In other words, I've created a schema as a package (as suggested in many points).

I wish, in a function of this schema, to be able to call each other functions of this schema without adding the schema name in the call instruction.

PostgreSQL isn't really designed for that - especially if you aren't formally creating an extension but simply putting stuff into a schema.

The script code you use to install your makeshift package should handle dynamic schema naming.  It's a pain, do you really need to allow the name of the schema to be unknown at installation time?

You should read up on how extensions are implemented - you are basically writing your own CREATE EXTENSION implementation.

https://www.postgresql.org/docs/current/extend-extensions.html#EXTEND-EXTENSIONS-RELOCATION

In any case, there really aren't any smarts here: explicitly schema qualify your function calls and forget that search_path even exists.  Unless you are writing custom operators, and even then, consider search_path to be evil.
