[pavel-zotov]

Following was checked on WI-T6.0.0.673 Firebird 6.0 7519f25:

Step-1: run script:

set bail on;
set echo on;
shell del c:\temp\tmp4test.fdb 2>nul;
create database 'localhost:c:\temp\tmp4test.fdb' user 'sysdba' password 'masterkey';
recreate view v_data as select 1 x from rdb$database;
commit;

Step-2:
make b/r
%FB_HOME%\gbak -b localhost:c:\temp\tmp4test.fdb stdout | %FB_HOME%\gbak -rep stdin localhost:c:\temp\tmp4test.restored.fdb

Step-3: run script which tries to recreate view on just restored DB

set bail on;
set echo on;
connect 'localhost:c:\temp\tmp4test.restored.fdb' user 'sysdba' password 'masterkey';
recreate view v_data as select 1 x from rdb$database;

Ouput will be:

connect 'localhost:c:\temp\tmp4test.restored.fdb' user 'sysdba' password 'masterkey';
show version;
