1.- Make "vec" type safe and get rid of several code contortions. Fix some small bugs meanwhile.
...
2.- Put inside PC_ENGINE several data members that belong to that feature.
3.- Put inside PC_ENGINE the code that does cleanup on those unused data members.

Don't allow to create primary key constraint on non-null fields with null values.
...
For example:
create table buggg (f1 int not null, f2 int not null);
commit;
insert into buggg values (1, 1)
commit;
alter table buggg add pk int not null primary key;
or
alter table buggg add constraint pk_buggg primary key (pk)
or
alter table buggg add constraint pk_buggg primary key (f1, f2, pk)

1) Fix starting with and empty string index problem where empty string is passed in parameter. (STARTING WITH ?) ? = ''
...
2) New index structure ensures that NULLs cannot hold the same key-value as a data value.
3) Ignore NULLs already on scanning index where possible.

Enhanced Index Structure.
...
1) NULLs on top when sorting on ASC index, DESC stays the same.
2) Support for larger index lengths, can be up to 1/4 page size.
3) Store record-number on non-leafpages for faster lookup in many duplicates.
4) Jump-nodes for faster key-lookup in index on larger page-sizes.
5) Segment selectivity calculation added.
