Running pgAdmin 4 V 1.0 against PostGres 9.6.0 OS: Windows 7 Pro x64 How to reproduce:
Start up pgAdmin4 Connect to your local server. Right-click on "Databases" and select "Create \ Database ..." The "Create - Database" dialog comes up. Enter "Test" as the database name and hit Save. The database is created. Navigate to "Test\Schemas\public\Tables" Right-click on "Tables" and select "Create\Table" The "Create - Table" dialog comes up. Enter "TestTable" as the table name and hit Save. The table is created. Right-click on database "Test" and select "Query Tool" In the query window enter: ALTER TABLE "TestTable" ADD COLUMN "A" text; Hit F5. The "Messages" section contains: ALTER TABLE Query returned successfully in 145 msec. Right-click on "Test\Schemas\public\Tables\TestTable\Columns" and select "Refresh" Column "A" has not been added. If you restart pgAdmin the column is still not there. Many Thanks, Adam Benson ==================
