İlk olarak, bu hatayla ilgili birkaç gönderi buldum ve çoğu bir RAM sorununa veya SSL sorununa işaret ediyor, komut satırına sslmode = devre dışı ekleyerek SSL olasılığını aşmayı denedim:
psql -U waypoint -d waypoint -W -c "alter table telemetria_data.historico alter clase type smallint, alter valor type real[], alter power type smallint, alter voltaje type real;" -h localhost -v sslmode=disableAncak aynı mesaj ortaya çıktı:
SSL SYSCALL error: EOF detected
connection to server was lostOlası bellek sorunuyla ilgili olarak, nasıl giderileceğini bilmiyorum.
Veri yapısı, bu soruda açıklanan yapıdır ve bulabileceğiniz gibi, bu, tüm miras alınan tablolar üzerinde tam değiştirme tablosunu tamamlamayı tamamlamak için çok uzun süren bir sorgu olacaktır.

PostgreSQL 9.4.9 on x86_64-unknown-linux-gnu, compiled by gcc (Debian 4.9.2-10) 4.9.2, 64-bitGüncelleme 2017-06-01 13:50 GMT
Komut şu şekilde değiştirildi (@ Daniel Vérité'nin önerileri nedeniyle):
time PGSSLMODE=disable psql -U waypoint -d waypoint -W -c "alter table telemetria_data.historico alter clase type smallint, alter valor type real[], alter power type smallint, alter voltaje type real;" -h localhostSorun aslında şu şekilde değiştirildi:
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
connection to server was lostGüncelleme 2017-06-01 15:34 GMT
Bunun gibi birkaç günlük girişi (in /var/log/postgresql/postgresql-9.4-main.log) bulundu :

Ayarlar şu şekilde değiştirildi:
checkpoint_segments = 100 # in logfile segments, min 1, 16MB each
checkpoint_timeout = 30s # range 30s-1h
Ve sabit sürücüyü doldurdum :( Cömertçe checkpoint_segments'ı artırdım, ancak önce kullanılabilir alanı kontrol etmedim. Neyse ki bu prosedürü üretim dışı bir ortamda test ediyorum. veya kullanılan geçici alanı boşaltmanın herhangi bir yolu var mı?

HINT: Check free disk space.@ Deszo'nun sorusuna göre, bellek fazla taahhüt değerleri aşağıdaki gibidir:

Sunucu örneği bir AWS c4.large (2 vCPU, 3.75 GB RAM)
Birkaç parametre daha from postgresql.conf:
shared_buffers = 2GB # min 128kB
work_mem = 32MB # min 64kB
max_connections =800 # (change requires restart)

Bir arka uç kazası gibi görünüyor. Bellek yetersiz bir durum olabilir. Postgresql sunucu günlüklerini kontrol edin ve işletim sistemi Linux ise ve OOM katili etkinse, çekirdek hata anında günlüğe kaydedilir.
