I will be glad to receive from you any example reproducing this problem.
I used the following script but there are no any warnings:
create table foo(pk bigint primary key, val bigint);
insert into foo values (generate_series(1,1000000), 0);
copy foo to '/tmp/foo.csv';
create table foo3(pk bigint, val bigint);
create index on foo3 using lsm3(pk);
copy foo3 from '/tmp/foo.csv';
May be you can modify this script or propose yours...
from lsm3.
Here is an example based on my schema with fake data and with non-indexd columns removed:
Download and uncompress this file, or you can generate example data using this program in golang:
fake-ping-generator.go
package main
import (
"encoding/csv"
"fmt"
"math/rand"
"os"
"time"
"github.com/google/uuid"
"syreclabs.com/go/faker"
)
var fakeEmails [20000]string
var fakeSerials [20000]string
// returns value odds% of the time, else empty string
func maybe(odds int, value string) string {
n := rand.Int() % 100
if n < odds {
return value
} else {
return ""
}
}
func main() {
for i := 0; i < 20000; i++ {
fakeEmails[i] = faker.Internet().UserName() + "@example.com"
fakeSerials[i] = faker.Lorem().Characters(7)
}
w := csv.NewWriter(os.Stdout)
var i int64
for {
w.Write([]string{
"9999",
time.Now().Add(time.Second * time.Duration(i/100)).Format("2006-01-02T15:04:05.000Z"),
faker.Internet().IpV4Address(),
maybe(10, uuid.New().String()),
time.Now().Add(time.Second * time.Duration(i/100+(rand.Int63()%60-30))).Format("2006-01-02T15:04:05.000Z"),
time.Now().Add(time.Second * time.Duration(i/100-rand.Int63()%604800)).Format("2006-01-02T15:04:05.000Z"),
fakeSerials[rand.Int()%20000],
faker.Internet().IpV4Address(),
maybe(50, faker.Internet().IpV6Address()),
fmt.Sprint(faker.Address().Latitude()),
fmt.Sprint(faker.Address().Longitude()),
fmt.Sprint(rand.Int() % 1000),
fmt.Sprint(rand.Int()%300, "Seconds"),
fakeEmails[rand.Int()%20000],
})
i++
}
}
Set up the database like this:
simplified-schema.sql
CREATE EXTENSION lsm3;
CREATE COLLATION case_insensitive
(provider = icu, locale = 'en-US-u-ks-level2');
CREATE TABLE pings
(
endpoint integer NOT NULL,
server_time timestamp with time zone NOT NULL DEFAULT CURRENT_TIMESTAMP,
request_ip character varying(250) COLLATE case_insensitive NOT NULL,
device_id uuid,
client_time timestamp with time zone,
session_start timestamp with time zone,
serial_number character varying(250) COLLATE case_insensitive,
local_ipv4 character varying(250) COLLATE case_insensitive,
local_ipv6 character varying(250) COLLATE case_insensitive,
latitude real,
longitude real,
accuracy real,
location_age interval,
email character varying(250) COLLATE case_insensitive
);
CREATE INDEX pings_accuracy_idx
ON pings USING lsm3
(endpoint ASC NULLS LAST, accuracy ASC NULLS LAST);
CREATE INDEX pings_client_time_idx
ON pings USING brin
(client_time);
CREATE INDEX pings_device_id_idx
ON pings USING lsm3
(endpoint ASC NULLS LAST, device_id ASC NULLS LAST, server_time DESC NULLS FIRST);
CREATE INDEX pings_email_idx
ON pings USING lsm3
(endpoint ASC NULLS LAST, email COLLATE case_insensitive ASC NULLS LAST, server_time DESC NULLS FIRST);
CREATE INDEX pings_latitude_idx
ON pings USING lsm3
(endpoint ASC NULLS LAST, latitude ASC NULLS LAST);
CREATE INDEX pings_local_ipv4_idx
ON pings USING lsm3
(endpoint ASC NULLS LAST, local_ipv4 ASC NULLS LAST, server_time DESC NULLS FIRST);
CREATE INDEX pings_local_ipv6_idx
ON pings USING lsm3
(endpoint ASC NULLS LAST, local_ipv6 ASC NULLS LAST, server_time DESC NULLS FIRST);
CREATE INDEX pings_location_age_idx
ON pings USING lsm3
(endpoint ASC NULLS LAST, location_age ASC NULLS LAST);
CREATE INDEX pings_longitude_idx
ON pings USING lsm3
(endpoint ASC NULLS LAST, longitude ASC NULLS LAST);
CREATE INDEX pings_request_ip_idx
ON pings USING lsm3
(endpoint ASC NULLS LAST, request_ip ASC NULLS LAST, server_time DESC NULLS FIRST);
CREATE INDEX pings_serial_number_idx
ON pings USING lsm3
(endpoint ASC NULLS LAST, serial_number COLLATE case_insensitive ASC NULLS LAST, server_time DESC NULLS FIRST);
CREATE INDEX pings_server_time_idx
ON pings USING brin
(server_time);
CREATE INDEX pings_session_start_idx
ON pings USING lsm3
(endpoint ASC NULLS LAST, session_start DESC NULLS FIRST, server_time DESC NULLS FIRST);
Do either something like COPY pings FROM '/tmp/test-data.csv' DELIMITER ',' CSV;
in psql or pgadmin 4. You should see something like "WARNING: you don't own a lock of type RowExclusiveLock" on stderr or in the messages tab of pgadmin.

Please try new version
from lsm3.
This resolved the issue. Thank you.
