Converting Json To Jsonb In Postgresql Technotrampoline Converting a column from json to jsonb and vice versa is fairly straightforward in postgresql. implicit casting is supported, a using clause does not need to be provided. alter column data set data type json; alter column data set data type jsonb;. In postgresql 9.4 the new jsonb was incorporated. on a live db in postgresql 9.3 i have a json column. i want to migrate it to jsonb. assuming i migrated the db first to 9.4 (using pg upgrade). what do i do next? alter column my json. set data type jsonb. using my json::jsonb; are there any benchmarks on how fast this is?.
Postgresql Jsonb Insert Function “how to start” is always a difficult question, and jsonb isn’t an exception. here are few notes about converting different types of data into jsonb, that someone can find useful. basically there are three possible cases of data conversion: convert data from inside postgresql convert data from other database convert plain data outside database.
