Is this a bug?
Executing of malformed (quote symbols) select in psql results in
unexpected behaviour:
pg01:5432 postgres@db=# select 'any expression'any expression\d+;

I tested psql-12 and psql-14 and I don't see this issue

You must have relations in search path, ifaiu.

it is expected result from my perspective
there is same error if you run your query without \d
postgres=# select 'any expression 'any expression;
ERROR: syntax error at or near "any"
LINE 1: select 'any expression 'any expression;

Thank you, i just was impressed by execution of part of malformed select
expression by psql as cli part.
