It is possible to define a global value/variable in PostgreSQL in a way that I can use it in any query/view/function?
For example, I do have a connection string I use for dblink connections in several places (specially, inside views).
Then, if I want to change the connection string, I do have to change every view manually.
If I can set a kind of global variable, then I just use it inside every view - then, at my application startup (or even at PostgreSQL startup, if I can set this string at postgresql.conf level), would set this "global variable" to point the current string.
Your enlightment will be really welcome.
