Nobody will read your post.

That turned out not to be the case :)

I was curious how much time it would take me to move such data in a postgres table (with apologies to the OP but I just can't be bothered with the minor oracle stuff).

It took me 13 minutes.

Obviously the parsing is guesswork on my part.

use strict;
use warnings;
use DBI;
my $t   = "pm1083865_ivo"; # table name
my $dbh = DBI->connect or die "no database connection - $!\n ";
$dbh->{AutoCommit} = 0;
$dbh->{RaiseError} = 1;
$dbh->do("drop table if exists $t");
$dbh->do("create table $t(col0 timestamptz, col1 text, col2 int, col3 
+text, col4 int)");
$dbh->commit;
my $sth1 = $dbh->prepare("insert into $t values(cast(? as timestamptz)
+,?,?)"    );
my $sth2 = $dbh->prepare("insert into $t values(cast(? as timestamptz)
+,?,?,?,?)");
my $date_string ;
while (<>) {
  chomp;
  $date_string = $_;
  last;
}
while (<>) {
  no warnings 'uninitialized';
  next if (/^\s*$/);
  my ($col1, $col2, $col3, $col4);
  s{\r}{};
  chomp;
  if ( /^([^:]+):\s*(\d+)\s*$/ )
  {
    $col1 = $1;
    $col2 = $2;
    $col3 = '';
    $col4 = '';
    $sth1->execute($date_string, $col1,$col2);
  }
  elsif ( /^([^:]+):\s*(\d+)\s*([^:]+):\s*(\d+)\s*$/ )
  {
    $col1 = $1;
    $col2 = $2;
    $col3 = $3;
    $col4 = $4;
    $sth2->execute($date_string,$col1,$col2,$col3,$col4);
  }
  else {
    print ">>>", $_ ,"<<<\n";
    die "oops - unprocessed line!\n";
  }
# print join("\t", $col1, $col2, $col3, $col4), "\n";
}
$dbh->commit;
$dbh->disconnect;

UPDATE: change col0 to timestamptz; added a commit;

Thanks Eric!

apology for the format, just first time user

That small typo 'fileds' (fields) obscured the meaning of your question for me, and rereading it I think that what you wanted is really more like this:

(again, I've implemented against postgres, but if you take out the DB stuff you can use CSV output (the outcommented lines))

use strict;
use warnings;
use DBI;
my $t   = "pm1083865_ivo2"; # table name
my $date_string ;
my @hdr = ();
my @val = ();
while (<>) {  # reading STDIN
  chomp;
  $date_string = $_;
  last;
}
while (<>) {  # reading STDIN
  next if (/^\s*$/);
  chomp;
  if ( /^([^:]+):\s*(\d+)\s*$/ ) {
    push(@hdr, $1); push(@val, $2); 
  }
  elsif ( /^([^:]+):\s*(\d+)\s*([^:]+):\s*(\d+)\s*$/ ) {
    push(@hdr, $1); push(@val, $2); 
    push(@hdr, $3); push(@val, $4); 
  }
  else {
    print ">>>", $_ ,"<<<\n";
    die "oops - unprocessed line!\n";
  }
}
# clean up header names for database use:
for (my$i=0;$i<scalar(@hdr);$i++) {
    $hdr[$i] = lc($hdr[$i]);  #  lower case
    $hdr[$i] =~ s{[-]}{_}g;   #  change dash to underscore
    $hdr[$i] =~ s{[ ]}{_}g;   #  change space to underscore
    $hdr[$i] =~ s{_[_]+}{_}g; #
}
my @all_hdrs = (); push(@all_hdrs, "date_line" ); push(@all_hdrs, @hdr
+);
my @all_vals = (); push(@all_vals, $date_string); push(@all_vals, @val
+);
# use only this line to get a output csv
# print join("\t", @all_hdrs), "\n", join("\t", @all_vals), "\n";
# exit;
my $dbh = DBI->connect or die "no database connection - $!\n ";
$dbh->{AutoCommit} = 0;
$dbh->{RaiseError} = 1;
my $arf = $dbh->selectrow_arrayref("
   select count(*) from information_schema.tables
   where table_schema = 'public' and table_name = '$t'");
if ($arf->[0] == 0) {
    my $sql_create = join("\n"
      , "create table $t ("
      ,  " date_line timestamptz\n, "
      ,  join ("\n, ", map { $_ .= ' integer' } @hdr )
      , ");"
    );
    $dbh->do( $sql_create );
}
my $sql_insert = join("\n"
      , "insert into $t values ("
      ,  join( ", ", map {'?'} @all_hdrs)
      , ");"
);
my $sth = $dbh->prepare($sql_insert);
my $rc  = $sth->execute(@all_vals);
$dbh->commit;
$dbh->disconnect;

After running that (showing record vertically):

$ echo "table pm1083865_ivo2" | psql -x | head -n 20
