Using a postgres image with mounted `/data` fails on LogWaitStrategy

Testcontainer:
version: 1.14.3

Postgres:
version: 5.6-alpine
output:

PostgreSQL Database directory appears to contain a database; Skipping initialization

LOG:  database system was interrupted; last known up at 2020-10-13 08:45:54 UTC
LOG:  database system was not properly shut down; automatic recovery in progress
LOG:  redo starts at 0/14F0430
LOG:  invalid record length at 0/3356CD0: wanted 24, got 0
LOG:  redo done at 0/3356CA8
LOG:  last completed transaction was at log time 2020-10-13 08:46:42.609873+00
LOG:  MultiXact member wraparound protections are now enabled
LOG:  database system is ready to accept connections
LOG:  autovacuum launcher started

Expected behavior:

• Container started successfully

Exception:

org.testcontainers.containers.ContainerLaunchException: Timed out waiting for log output matching '.*database system is ready to accept connections.*\s'
	at org.testcontainers.containers.wait.strategy.LogMessageWaitStrategy.waitUntilReady(LogMessageWaitStrategy.java:31)

Issue:
Because the image skep the initialization and the code on PostgresSQLContainer:56 is registering the LogMessageWaitStrategy to match the line ".*database system is ready to accept connections.*\\s" twice withTimes(2), the container readiness check fails.

Bắt đầu tại modules/postgresql/src/main/java/org/testcontainers/containers/PostgreSQLContainer.java, ở phần đăng ký wait-strategy được tham chiếu, sau đó đọc LogMessageWaitStrategy.waitUntilReady. Tái hiện trường hợp này với một container PostgreSQL sử dụng thư mục /data được mount và xác minh rằng quá trình khởi động hoàn tất mà không gặp readiness timeout.
