Hello Peter
I am looking on your patch.
I found only one issue
in documentation is role name or keyword ALL marked as optional, but
it is mandatory
+ALTER ROLE [ <replaceable class="PARAMETER">name</replaceable> | ALL
] [ IN DATABASE <replaceable
class="PARAMETER">database_name</replaceable> ] SET
<replaceable>configuration_parameter</replaceable> FROM CURRENT
+ALTER ROLE [ <replaceable class="PARAMETER">name</replaceable> | ALL
] [ IN DATABASE <replaceable
class="PARAMETER">database_name</replaceable> ] RESET
<replaceable>configuration_parameter</replaceable>
+ALTER ROLE [ <replaceable class="PARAMETER">name</replaceable> | ALL
] [ IN DATABASE <replaceable
class="PARAMETER">database_name</replaceable> ] RESET ALL
should be
+ALTER ROLE { <replaceable class="PARAMETER">name</replaceable> | ALL
} [ IN DATABASE <replaceable
class="PARAMETER">database_name</replaceable> ] SET
<replaceable>configuration_parameter</replaceable> FROM CURRENT
+ALTER ROLE { <replaceable class="PARAMETER">name</replaceable> | ALL
} [ IN DATABASE <replaceable
class="PARAMETER">database_name</replaceable> ] RESET
<replaceable>configuration_parameter</replaceable>
+ALTER ROLE { <replaceable class="PARAMETER">name</replaceable> | ALL
} [ IN DATABASE <replaceable
class="PARAMETER">database_name</replaceable> ] RESET ALL
???
