Hi,
I installed sqlite_fdw(https://github.com/pgspider/sqlite_fdw) on my postgresql v9.6.
As mentioned on the github page, the extension supports writes.
However, When I try to insert record into my foreign table my postgresql crushes :
sqlite> .schema MARIEL_TEST
CREATE TABLE MARIEL_TEST( cola INTEGER PRIMARY KEY, colb TEXT, colc INTEGER);
db=# CREATE FOREIGN TABLE MARIEL_TEST_foreign(cola integer, colbtext,colc integer) SERVER sqlite_server OPTIONS (table 'MARIEL_TEST');
CREATE FOREIGN TABLE
afa=# insert into MARIEL_TEST_foreign values(1,1,1);
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
!>
!> .exit
-> ;
You are currently not connected to a database.
As you can see the database crashed. Does the reason is the extension or something that I should investigate on the database itself ?
Moreover I tried to update the table and I'm getting the following error :
update MARIEL_TEST_foreign set ip=5 where vipid=2;
ERROR: no primary key column specified for foreign table
DETAIL: For UPDATE or DELETE, at least one foreign table column must be marked as primary key column.
HINT: Set the option "key" on the columns that belong to the primary key.
foreign tables dont support primary key :
CREATE FOREIGN TABLE MARIEL_TEST_foreign(id int primary key ) SERVER sqlite_server OPTIONS (table 'MARIEL_TEST');
ERROR: primary key constraints are not supported on foreign tables
so how can I update/delete a foreign table that has primary key ? OR with that extension it isnt an option ?
Thanks , Mariel.
