postgresql-9.2

Does anyone know what is the limit on the size of JSON data type in PostgreSQL 9.2? Looking at the source for PostgreSQL 9.2.1: Source: postgresql-9.2.1\src\backend\utils\adt\json.c: /* * Input. */ Datum json_in(PG_FUNCTION_ARGS) { char *text = PG_GETARG_CSTRING(0); json_validate_cstring(text); /* Internal representation is the same as text, for now */ PG_RETURN_TEXT_P(cstring_to_text(text)); } Update for PostgreSQL 9.3.5: The code has changed in the json_in function, but the json internal representation is still text: Source: postgresql-9.3.5\src\backend\utils\adt\json.c: /* * Input. */ Datum

In PostgreSql 9.2.4 I have two tables: user (id, login, password, name) and dealer (id, user_id) . And I want to insert into both tables returning id of created dealer. Currently I'm doing it with two queries: WITH rows AS ( INSERT INTO "user" (login, password, name) VALUES ('dealer1', 'jygbjybk', 'Dealer 1') RETURNING id ) INSERT INTO dealer (user_id) SELECT id FROM rows; SELECT currval('dealer_id_seq'); But can I implement this with a single INSERT query using RETURNING statement? You just need to add a RETURNING id to your INSERT ... SELECT : WITH rows AS (...) INSERT INTO dealer (user_id)

Whenever I try to drop database I get: ERROR: database "pilot" is being accessed by other users DETAIL: There is 1 other session using the database. When I use: SELECT pg_terminate_backend(pg_stat_activity.pid) FROM pg_stat_activity WHERE pg_stat_activity.datname = 'TARGET_DB'; I terminated the connection from that DB, but if I try to drop database after that somehow someone automatically connects to that database and gives this error.
