Zitat von Pavel Stehule <pavel.stehule@gmail.com>:

No, there is not possible to read/write client side variables from server
side.

 I did not mean that the variable be replaced by its value at execution time but at Installation time.

no. The :xxx is not evaluated inside string. The workaround is using GUC variables and related functions. Can be used from psql and from plpgsql too.
