Claim 23:
24. The one or more computer-readable storage media of claim 21, further comprising:
computer-executable instructions that, when executed by the computing system, cause the computing system to, at the node, in response to determining that the availability status of the replica node has changed, increment an identifier maintained by the node;
computer-executable instructions that, when executed by the computing system, cause the computing system to, at the node, compare the incremented identifier with a version timestamp associated with the prepared statement; and
computer-executable instructions that, when executed by the computing system, cause the computing system to, at the node, determine that the version timestamp identifier is associated with an earlier state of the database system than a state of the database system associated with the incremented identifier;
wherein the computer-executable instructions that cause the computing system to update the prepared statements are executed in response to determining that the version timestamp identifier is associated with an earlier state of the database system.
