regression=# \set VERBOSITY verbose
regression=# create table t1 (f1 int);
CREATE TABLE
regression=# create index t1i on t1(f1);
CREATE INDEX
regression=# create index t1i on t1(f1);
ERROR:  42P07: relation "t1i" already exists
LOCATION:  index_create, index.c:567

Evidently it's ERRCODE_DUPLICATE_TABLE.
