PSQL bug?

Made a typo, using } instead of ) to test a weird table name, and got
disconnected. Normal? --DD

ddevienne=> create table "t |" ( id int};
ddevienne(> );
server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Succeeded.
ddevienne=> create table "t |" ( id int);
ddevienne=> drop table "t |";
ddevienne=> \! psql -V
psql (PostgreSQL) 12.1
ddevienne=> select version();
                                                 version
