This change prevents problems when there are multiple connections

using OpenSSL within a single process and not all the code involved

follows the same rules for when to clear the error queue.

Failures have been reported specifically when a client application

uses SSL connections in <application>libpq</> concurrently with

SSL connections using the PHP, Python, or Ruby wrappers for OpenSSL.
|

It's possible for similar problems to arise within the server as well,

if an extension module establishes an outgoing SSL connection.

In such a case, the operator family was restored into the new database,

immediate ill effects, but would cause later <application>pg_dump</>

<para>

Given a three-or-more-way equivalence class of variables, such
|

|
as <literal>X.X = Y.Y = Z.Z</>, it was possible for the planner to omit
|
||||||
|
some of the tests needed to enforce that all the variables are actually
|
||||||
|
equal, leading to join rows being output that didn't satisfy
|
||||||
|
the <literal>WHERE</> clauses. For various reasons, erroneous plans
|
||||||
|
were seldom selected in practice, so that this bug has gone undetected
|
||||||
|
for a long time.

Given a three-or-more-way equivalence class of variables, such

as <literal>X.X = Y.Y = Z.Z</>, it was possible for the planner to omit

some of the tests needed to enforce that all the variables are actually

equal, leading to join rows being output that didn't satisfy

the <literal>WHERE</> clauses. For various reasons, erroneous plans

Clear the OpenSSL error queue before OpenSSL calls, rather than

Failures have been reported specifically when a client application

uses SSL connections in <application>libpq</> concurrently with

SSL connections using the PHP, Python, or Ruby wrappers for OpenSSL.
|

It's possible for similar problems to arise within the server as well,

if an extension module establishes an outgoing SSL connection.

recently back-patched a fix that expected the barrier code to work

affected.
