PostgreSQL:“；警告：共享内存不足“；关于简单选择

每当我尝试在我的Postgres db上进行简单选择时，我都会遇到以下错误：

tutorial=> select id from table LIMIT 1;

我尝试将“max\u locks\u per\u transaction”增加到256，增加了所有内存参数，但不起任何作用。命令只是花了更长的时间才返回

在几个月的时间里，一切都很好，然后这个问题出现了，我无法跟踪日志来发现发生了什么

以下是出现问题时的引导顺序，当出现此问题时，我尝试重新引导postgres后：

LOG:  database system was not properly shut down; automatic recovery in progress
LOG:  redo starts at 2/2C7A1580
LOG:  invalid record length at 2/2C848AC8: wanted 24, got 0
LOG:  redo done at 2/2C848AA0
LOG:  last completed transaction was at log time 2018-01-29 14:38:52.726603+00
LOG:  MultiXact member wraparound protections are now enabled
LOG:  database system is ready to accept connections
LOG:  autovacuum launcher started

我的数据库实现了TimescaleDB和PostGIS插件，仅由一个表组成。 我可以执行所有其他语句（插入、更新等），但SELECT不起作用，而且非常烦人

它只涉及这个超表格。我只有表spatial\u ref\u sys在它旁边，我对这个没有问题

通过解释，我得到了完全相同的行为，没有任何信息记录：

tutorial=> EXPLAIN SELECT id FROM table LIMIT 1;
WARNING:  out of shared memory
ERROR:  out of shared memory
HINT:  You might need to increase max_locks_per_transaction.

服务器是一个Debian 2x86 64位内核和2GB内存。 我使用docker按照以下步骤设置此数据库：

以下是我用来设置数据库的说明：

CREATE EXTENSION IF NOT EXISTS timescaledb CASCADE;
CREATE EXTENSION postgis; 
CREATE EXTENSION postgis_topology;
CREATE TABLE "public"."table" (
    "id" BIGSERIAL NOT NULL PRIMARY KEY,
    "id_s" int8 NOT NULL,
    "id_g" int8,
    "datetime" TIMESTAMPTZ DEFAULT now(),
    [...]
);
SELECT create_hypertable('table', 'datetime');
ALTER TABLE table ADD CONSTRAINT id_pkey PRIMARY KEY (id, datetime);
CREATE INDEX ON table (id_s, datetime DESC);
CREATE INDEX ON table (id_g, datetime DESC);
ALTER TABLE table ADD COLUMN geom geometry(POINT,2192)
