Simplified (a-la [G|N]DBM) DB access

Good day,

excuse me, if my question is lame, but is it possible to get some 
simplified access to the PostgreSQL?

What I mean is: currently to get/put/delete/edit any data I have to 
compose an SQL query, which should be parsed, compiled, optimized and 
so on. While, in some tasks simple interface a-la [G|N]DBM should be 
more than enough, but it will be more preferable to store all data in 
one database, which support concurrent access, transactions, etc.

For example, let me have some textual data in PostgreSQL, and let me 
wish to have an inverted index for some statistical analyses purpose 
(for example, search, but without using tsearch2). For now, to make any 
operations with all that data, I have to use an SQL, which makes such 
thing really slow (take a look at sql-mode mnogosearch and others).
Yes, I can store all that data outside the db, but I will have to 
reinvent all the features, which realized great in PostgreSQL (for 
example, recovery, transactions) and I will get harder administrative 
support, backup and so on.

Thank you in advance,
Regards,
/Alexandre.
