Fix subtransaction cleanup after a portal (cursor) belonging to an

outer subtransaction fails (Tom Lane, Michael Paquier)

A function executed in an outer-subtransaction cursor could cause an

An oversight in a patch in the most recent minor releases
|
||||||
|
caused <structname>pg_trigger_tgrelid_tgname_index</> to be omitted
|
||||||
|
from the init file. Subsequent sessions detected this, then deemed the
|
||||||
|
init file to be broken and silently ignored it, resulting in a
|
||||||
|
significant degradation in session startup time. In addition to fixing
|
||||||
|
the bug, install some guards so that any similar future mistake will be
|
||||||
|
more obvious.

Disable SSL renegotiation by default (Michael Paquier, Andres Freund)

</para>
|

<para>
|
||||||
|
While use of SSL renegotiation is a good idea in theory, we have seen
|
||||||
|
too many bugs in practice, both in the underlying OpenSSL library and
|
||||||
|
in our usage of it. Renegotiation will be removed entirely in 9.5 and
|
||||||
|
later. In the older branches, just change the default value
|
||||||
|
of <varname>ssl_renegotiation_limit</> to zero (disabled).

This is mainly to make tests of related behavior less time-consuming,

Fix assorted planner bugs (Tom Lane)

</para>
|

<para>
|

These mistakes could lead to incorrect query plans that would give wrong

|
answers, or to assertion failures in assert-enabled builds, or to odd
|
||||||
|
planner errors such as <quote>could not devise a query plan for the

|
given query</>, <quote>could not find pathkey item to
|
||||||
|
sort</>, <quote>plan should not reference subplan's variable</>,
|

|
or <quote>failed to assign all NestLoopParams to plan nodes</>.

If, during a crash recovery cycle, the startup process crashes without

having restored database consistency, we'd try to launch a new startup

process, which typically would just crash again, leading to an infinite

loop.

Fix <application>pg_dump</> to handle object privileges sanely when

Fix subtransaction cleanup after a portal (cursor) belonging to an

An oversight in a patch in the most recent minor releases

caused <structname>pg_trigger_tgrelid_tgname_index</> to be omitted
|

from the init file. Subsequent sessions detected this, then deemed the

|
init file to be broken and silently ignored it, resulting in a
|
||||||
|
significant degradation in session startup time. In addition to fixing
|
||||||
|
the bug, install some guards so that any similar future mistake will be
|
||||||
|
more obvious.

Disable SSL renegotiation by default (Michael Paquier, Andres Freund)

</para>
|

<para>
|

|
While use of SSL renegotiation is a good idea in theory, we have seen
|
||||||
|
too many bugs in practice, both in the underlying OpenSSL library and
|
||||||
|
in our usage of it. Renegotiation will be removed entirely in 9.5 and
|
||||||
|
later. In the older branches, just change the default value
|
||||||
|
of <varname>ssl_renegotiation_limit</> to zero (disabled).

Fix assorted planner bugs (Tom Lane)

</para>
|

|
<para>
|

|
These mistakes could lead to incorrect query plans that would give wrong
|
||||||
|
answers, or to assertion failures in assert-enabled builds, or to odd
|
||||||
|
planner errors such as <quote>could not devise a query plan for the
|
||||||
|
given query</>, <quote>could not find pathkey item to
|
||||||
|
sort</>, <quote>plan should not reference subplan's variable</>,
|
||||||
|
or <quote>failed to assign all NestLoopParams to plan nodes</>.
|
||||||

Thanks are due to Andreas Seltenreich and Piotr Stefaniak for fuzz
|
||||||
|
testing that exposed these problems.

Fix <application>pg_dump</> to handle object privileges sanely when

When dumping functions or procedural languages from pre-7.3

|
servers, <application>pg_dump</> would
|

produce <command>GRANT</>/<command>REVOKE</> commands that revoked the

owner's grantable privileges and instead granted all privileges
|

to <literal>PUBLIC</>. Since the privileges involved are

just <literal>USAGE</> and <literal>EXECUTE</>, this isn't a security
|

problem, but it's certainly a surprising representation of the older

systems' behavior. Fix it to leave the default privilege state alone
|

in these cases.

An oversight in a patch in the most recent minor releases

caused <structname>pg_trigger_tgrelid_tgname_index</> to be omitted

init file to be broken and silently ignored it, resulting in a

|
significant degradation in session startup time. In addition to fixing
|
||||||
|
the bug, install some guards so that any similar future mistake will be
|

more obvious.

<para>
|

While use of SSL renegotiation is a good idea in theory, we have seen

too many bugs in practice, both in the underlying OpenSSL library and
|
||||||
|
in our usage of it. Renegotiation will be removed entirely in 9.5 and
|
||||||
|
later. In the older branches, just change the default value
|

|
of <varname>ssl_renegotiation_limit</> to zero (disabled).

Fix <application>pg_dump</> to handle object privileges sanely when

When dumping data types from pre-9.2 servers, and when dumping

functions or procedural languages from pre-7.3

servers, <application>pg_dump</> would

owner's grantable privileges and instead granted all privileges

just <literal>USAGE</> and <literal>EXECUTE</>, this isn't a security

in these cases.
