> It seems that there is a problem with schema names that start with a number followed by a dot.
> Please take a look at the following script. Everything works fine but the last line which is a delete statement. Note that having the foreign key constraints was necessary to make it reproduce the problem.
> create schema "1.a";
> create table "1.a"."role"
> (
> "id" integer generated always as identity,
> "name" varchar(255) not null
> );
> alter table "1.a"."role" add constraint "role_pk"
> primary key ("id");
> create table "1.a"."user"
> (
> "id" integer generated always as identity,
> "name" varchar(255) not null
> );
> alter table "1.a"."user" add constraint "user_pk"
> primary key ("id");
> create table "1.a"."user_role"
> (
> "role" integer not null,
> "user" integer not null
> );
> alter table "1.a"."user_role" add constraint "user_role_fk1"
> foreign key ("role")
> references "1.a"."role" ("id")
> on delete cascade;
> alter table "1.a"."user_role" add constraint "user_role_fk2"
> foreign key ("user")
> references "1.a"."user" ("id")
> on delete cascade;
> alter table "1.a"."user_role" add constraint "user_role_u1"
> unique ("user", "role");
> insert into "1.a"."role" ("name") values ('r1');
> insert into "1.a"."user" ("name") values ('u1');
> insert into "1.a"."user_role" ("role","user") values (1,1);
> select * from "1.a"."user";
> delete from "1.a"."user";
> Last delete statement fails. The error is:
> Schema '1' does not exist [SQL State=42Y07, DB Errorcode=20000]
