Forcing "quotes" around Value field in database Parameters sheet

Hi good people  :)

I may have found a bug in the *Database properties* sheet preventing 
setting *Parameters* on the database level.

I tried to set the *search_path* parameter on the database level.

 1. Right click on the database
 2. Select *Properties...* from the menu
 3. Click on tab *Parameters*
 4. Click *+* and enter /search_path/ to *Name* field
 5. Enter /scha, schb, public, pg_catalog**/in the *Value *field (note,
    without quotes)
 6. Click *Save*

Run new query window and type *show search_path*. The result is 
*"**scha, schb, public, pg_catalog"* - together with the quotes aroud 
the string.*
*Such path, of course, is not valid.

Testing this in the same query window:

*SET search_path TO scha, schb, public, pg_catalog*;

*SHOW search_path*

results with

*scha, schb, public, pg_catalog* (without quotes, and it works as expected).

My conclusion is that pgAdmin4 for some reason adds and stores quotes 
around the search_path value, and later uses the value as if it is a 
*single full path name*.

The database server this occures on is Pg 11.

Best regards,

M.O.
