Don't error out if recycling or removing an old WAL file fails at the |

It's better to treat the problem as non-fatal and allow the checkpoint |
|
|
|
|
to complete. Future checkpoints will retry the removal. Such problems |
|
|
|
|
are not expected in normal operation, but have been seen to be |
|
|
|
|
caused by misdesigned Windows anti-virus and backup software. |

The previous code is known to fail with the combination of the Linux |

|
<literal>pam_krb5</> PAM module with Microsoft Active Directory as the |
|
|
|

domain controller. It might have problems elsewhere too, since it was |

|
|

making unjustified assumptions about what arguments the PAM stack would |
|
|
|
|
pass to it. |
