We have a precode for interpreter (all interpreters) which executes once after start interpreter. With it we can create shared code that will be available in the paragraph, create tables in the database and etc.
This precode for jdbc only which executes before run paragraph in same session (sql). In this precode we can declare session variables that will be available when you run paragraph (any sql which will be executed before the paragraph). For example `set application_name='#{user};`
Previous discussion in #2442

(jdbc interpreter, postgres)
1. set property **default.statementPrecode** `set application_name='#{user}';`
2. run paragraph `select current_setting('application_name');`
* Does the licenses files need update? no
* Is there breaking changes for older versions? no
* Does this needs documentation? no
