Adapt to CURRENT_TIMESTAMP(x) default values.

Browse Source 
We target CURRENT_TIMESTAMP as the PostgreSQL default value for columns
when it was different before on the grounds that the type casting in
PostgreSQL is doing the job, as in the following example:

    pgloader# create table test_ts(ts timestamptz(6) not null default CURRENT_TIMESTAMP);
    CREATE TABLE
    pgloader# insert into test_ts VALUES(DEFAULT);
    INSERT 0 1
    pgloader# table test_ts;
                  ts
    -------------------------------

    pgloader# drop table test_ts;
    DROP TABLE
    pgloader# create table test_ts(ts timestamptz(0) not null default CURRENT_TIMESTAMP);
    CREATE TABLE
    pgloader# insert into test_ts VALUES(DEFAULT);
    INSERT 0 1
    pgloader# table test_ts;
               ts
