Thanks.
So the implicit value means that PG gave it a name?

Hello
Just trying to play around with PostgreSQL. Some commands and their
result are:
test=# create table ncbi ( id serial, title varchar(50), abstract text,
primary key(id));
NOTICE: CREATE TABLE will create implicit sequence "ncbi_id_seq" for
serial column "ncbi.id"
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index
"ncbi_pkey" for table "ncbi"
CREATE TABLE
test=# drop table ncbi;
DROP TABLE
test=# create table ncbi ( id serial, title varchar(50), abstract text);
NOTICE: CREATE TABLE will create implicit sequence "ncbi_id_seq" for
serial column "ncbi.id"
CREATE TABLE
======
q1) Does 'implicit index' means that they have given a default name to
the PK which I defined in the first query since I didnt give a name or
does it mean one another index is created apart from the PRIMARY KEY?
It only creates one index, the primary key index.
