have @ create type

create type stringintpairtype (k string,v int);

update: here full example of how accomplish pg sql

define element type of dictionary

create type stringintpairtype (k text,v int);

create sample table. note collection column marked '[]' @ end

create table collectionstables (   id serial unique,   collection  stringintpairtype[],   description text,   ts timestamp not null default now() )

inserts single record 2 dictionary elements

insert collectionstables(collection,description) values (     array     [        ('test1',1)::stringintpairtype,        ('test2',2)::stringintpairtype     ],     'description1' );

inserts single record 2 dictionary elements

insert collectionstables(collection,description) values         (             array             [                ('testa',30)::stringintpairtype,                ('testb',40)::stringintpairtype             ],             'description2'         );

note regular table other table

select * collectionstables

select collection[1].k,description collectionstables
