With current sources:
regression=> create table t1 ( f1 serial primary key );
NOTICE: CREATE TABLE will create implicit sequence t1_f1_seq for SERIAL column t1.f1
NOTICE: CREATE TABLE/PRIMARY KEY will create implicit index t1_pkey for table t1
CREATE
OK so far ...
regression=> create table t2 ( f1 serial,
regression-> primary key (f1) );
NOTICE: CREATE TABLE will create implicit sequence t2_f1_seq for SERIAL column t2.f1
NOTICE: CREATE TABLE/UNIQUE will create implicit index t2_f1_key for table t2
NOTICE: CREATE TABLE/PRIMARY KEY will create implicit index t2_pkey for table t2
CREATE
And, indeed, it's made two separate indexes on t2's f1 field. This is
a bug, no?
