Fix a race condition that could cause indexes built
|

|
with <command>CREATE INDEX CONCURRENTLY</> to be corrupt

(Pavan Deolasee, Tom Lane)

<para>
|

If <command>CREATE INDEX CONCURRENTLY</> was used to build an index
|
||||||
|
that depends on a column not previously indexed, then rows inserted
|
||||||
|
or updated by transactions that ran concurrently with
|
||||||
|
the <command>CREATE INDEX</> command could have received incorrect
|
||||||
|
index entries. If you suspect this may have happened, the most
|
||||||
|
reliable solution is to rebuild affected indexes after installing
|
||||||
|
this update.

This fix avoids problems when autovacuum is nominally off and there

Extension upgrade scripts should be able to drop member objects,

Fix processing of OID column when a table with OIDs is associated to

Langote)
|

|

<para>

The OID column should be treated the same as regular user columns in

this case, but it wasn't, leading to odd behavior in later
|

inheritance changes.

Check for serializability conflicts before reporting
|
||||||
|
constraint-violation failures (Thomas Munro)
|
||||||
|
</para>
|
||||||
|
|
||||||
|
<para>
|
||||||
|
When using serializable transaction isolation, it is desirable
|
||||||
|
that any error due to concurrent transactions should manifest
|
||||||
|
as a serialization failure, thereby cueing the application that
|
||||||
|
a retry might succeed. Unfortunately, this does not reliably
|
||||||
|
happen for duplicate-key failures caused by concurrent insertions.
|
||||||
|
This change ensures that such an error will be reported as a
|
||||||
|
serialization error if the application explicitly checked for
|
||||||
|
the presence of a conflicting key (and did not find it) earlier
|
||||||
|
in the transaction.

Ensure that column typmods are determined accurately for

multi-row <literal>VALUES</> constructs (Tom Lane)
|

|
</para>
|
||||||
|
|
||||||
|
<para>
|
||||||
|
This fixes problems occurring when the first value in a column has a
|
||||||
|
determinable typmod (e.g., length for a <type>varchar</> value) but
|
||||||
|
later values don't share the same limit.

Throw error for an unfinished Unicode surrogate pair at the end of a

|
Unicode string (Tom Lane)
|
||||||
|
</para>
|
||||||
|
|
||||||
|
<para>
|
||||||
|
Normally, a Unicode surrogate leading character must be followed by a
|
||||||
|
Unicode surrogate trailing character, but the check for this was
|
||||||
|
missed if the leading character was the last character in a Unicode
|
||||||
|
string literal (<literal>U&'...'</>) or Unicode identifier
|

|
(<literal>U&"..."</>).

In some cases, a cast that should result in zeroing out

Fix a race condition that could cause indexes built
|

|
with <command>CREATE INDEX CONCURRENTLY</> to be corrupt
|

|
(Pavan Deolasee, Tom Lane)

<para>
|

If <command>CREATE INDEX CONCURRENTLY</> was used to build an index
|
||||||
|
that depends on a column not previously indexed, then rows inserted
|
||||||
|
or updated by transactions that ran concurrently with
|
||||||
|
the <command>CREATE INDEX</> command could have received incorrect
|
||||||
|
index entries. If you suspect this may have happened, the most
|
||||||
|
reliable solution is to rebuild affected indexes after installing
|
||||||
|
this update.

Check for serializability conflicts before reporting
|

|
constraint-violation failures (Thomas Munro)
|
||||||
|
</para>
|
||||||
|
|
||||||
|
<para>
|
||||||
|
When using serializable transaction isolation, it is desirable
|
||||||
|
that any error due to concurrent transactions should manifest
|
||||||
|
as a serialization failure, thereby cueing the application that
|
||||||
|
a retry might succeed. Unfortunately, this does not reliably
|
||||||
|
happen for duplicate-key failures caused by concurrent insertions.
|
||||||
|
This change ensures that such an error will be reported as a
|
||||||
|
serialization error if the application explicitly checked for
|
||||||
|
the presence of a conflicting key (and did not find it) earlier
|
||||||
|
in the transaction.

This fixes problems occurring when the first value in a column has a

later values don't share the same limit.

Normally, a Unicode surrogate leading character must be followed by a

Fix a race condition that could cause indexes built
|

with <command>CREATE INDEX CONCURRENTLY</> to be corrupt

<para>
|

If <command>CREATE INDEX CONCURRENTLY</> was used to build an index
|
||||||
|
that depends on a column not previously indexed, then rows inserted
|
||||||
|
or updated by transactions that ran concurrently with
|
||||||
|
the <command>CREATE INDEX</> command could have received incorrect
|
||||||
|
index entries. If you suspect this may have happened, the most
|
||||||
|
reliable solution is to rebuild affected indexes after installing
|
||||||
|
this update.

Backends failed to account for this snapshot when advertising their

Check for serializability conflicts before reporting

|
constraint-violation failures (Thomas Munro)
|

|
</para>
|
||||||
|
|
||||||
|
<para>
|
||||||
|
When using serializable transaction isolation, it is desirable
|
||||||
|
that any error due to concurrent transactions should manifest
|
||||||
|
as a serialization failure, thereby cueing the application that
|
||||||
|
a retry might succeed. Unfortunately, this does not reliably
|
||||||
|
happen for duplicate-key failures caused by concurrent insertions.
|
||||||
|
This change ensures that such an error will be reported as a
|
||||||
|
serialization error if the application explicitly checked for
|
||||||
|
the presence of a conflicting key (and did not find it) earlier
|
||||||
|
in the transaction.

Fix a race condition that could cause indexes built

If <command>CREATE INDEX CONCURRENTLY</> was used to build an index

|
that depends on a column not previously indexed, then rows inserted
|
||||||
|
or updated by transactions that ran concurrently with
|
||||||
|
the <command>CREATE INDEX</> command could have received incorrect
|
||||||
|
index entries. If you suspect this may have happened, the most
|
||||||
|
reliable solution is to rebuild affected indexes after installing
|
||||||
|
this update.

Check for serializability conflicts before reporting

|
constraint-violation failures (Thomas Munro)
|

|
</para>
|
||||||
|
|
||||||
|
<para>
|
||||||
|
When using serializable transaction isolation, it is desirable
|
||||||
|
that any error due to concurrent transactions should manifest
|
||||||
|
as a serialization failure, thereby cueing the application that
|
||||||
|
a retry might succeed. Unfortunately, this does not reliably
|
||||||
|
happen for duplicate-key failures caused by concurrent insertions.
|
||||||
|
This change ensures that such an error will be reported as a
|
||||||
|
serialization error if the application explicitly checked for
|
||||||
|
the presence of a conflicting key (and did not find it) earlier
|
||||||
|
in the transaction.

Avoid discarding <type>interval</>-to-<type>interval</> casts

In some cases, a cast that should result in zeroing out

low-order <type>interval</> fields was mistakenly deemed to be a

|
no-op and discarded. An example is that casting from <type>INTERVAL

MONTH</> to <type>INTERVAL YEAR</> failed to clear the months field.
