How can I use an environment variable in a Postgres function?
Let's say I have a windows user environment variable SOME_STRING.
Is it possible to use its value in a PL/pgSQL function?
If not, do I need to use an untrusted language (like PL/pythonu) or can I use a trusted one?
I am on PG 9.2
postgresql plpgsql environment-variables

You can not access a environment variable directly; but you can access a custom configuration setting and set that to a value from the environment at startup. For example, you can pass the follow startup option using PGOPTIONS
:
PGOPTIONS="-c 'custom.some_string=${SOME_STRING}'"
Note: the dot (.
) in the name is important.
Then retrieve the value using current_setting
:
SELECT current_setting('custom.some_string');
(I have tried this on Linux and found it to be working, it should be the same for Windows, but may need some slight modification to cater of that particular platform.)
