```
    Protects current statement from cancelTask starting, waiting for a bit, and waking up exactly on subsequent query execution. The idea is to atomically compare and swap the reference to the task, so the task can detect that statement executes different query than the one the cancelTask was created. Note: the field must be set/get/compareAndSet via CANCEL_TIMER_UPDATER as per AtomicReferenceFieldUpdater javadoc.

```
private static final java.util.concurrent.atomic.AtomicReferenceFieldUpdater<PgStatement,java.util.TimerTask> CANCEL_TIMER_UPDATER
```
  - statementState
```
private volatile StatementCancelState statementState
```
    Protects statement from out-of-order cancels. It protects from both setQueryTimeout(int) and cancel() induced ones. execute(String) and friends change the field to StatementCancelState.IN_QUERY during execute. cancel() ignores cancel request if state is StatementCancelState.IDLE. In case execute(String) observes non-StatementCancelState.IDLE state as it completes the query, it waits till StatementCancelState.CANCELLED. Note: the field must be set/get/compareAndSet via STATE_UPDATER as per AtomicIntegerFieldUpdater javadoc.

public void setQueryTimeoutMs(long millis)

    Sets the queryTimeout limit.

  - addWarning
```
public void addWarning(java.sql.SQLWarning warn)
```
    Either initializes new warning wrapper, or adds warning onto the chain.
    
    Although warnings are expected to be added sequentially, the warnings chain may be cleared concurrently at any time via clearWarnings(), therefore it is possible that a warning added via this method is placed onto the end of the previous warning chain
    
    Parameters:
    
    warn - warning to add

  - clearWarnings
```
public void clearWarnings()
                   throws java.sql.SQLException
```
    Clears the warning chain.
    
    Note that while it is safe to clear warnings while the query is executing, warnings that are added between calls to getWarnings() and #clearWarnings() may be missed. Therefore you should hold a reference to the tail of the previous warning chain and verify if its SQLWarning.getNextWarning() value is holds any new value.
    
    Specified by:

public long getLastOID()

  - setPrepareThreshold
```
public void setPrepareThreshold(int newThreshold)
                         throws java.sql.SQLException
```
    Description copied from interface: PGStatement
    
    Sets the reuse threshold for using server-prepared statements.
    
    If threshold is a non-zero value N, the Nth and subsequent reuses of a PreparedStatement will use server-side prepare.
    
    If threshold is zero, server-side prepare will not be used.
    
    The reuse threshold is only used by PreparedStatement and CallableStatement objects; it is ignored for plain Statements.
    
    Specified by:
    
    setPrepareThreshold in interface PGStatement
    
    Parameters:
    
    newThreshold - the new threshold for this statement
    
    Throws:
    
    java.sql.SQLException - if an exception occurs while changing the threshold
  - getPrepareThreshold

    Specified by:
    
    getPrepareThreshold in interface PGStatement
    
    Returns:

public void setUseServerPrepare(boolean flag)

    Description copied from interface: PGStatement
    
    Turn on the use of prepared statements in the server (server side prepared statements are unrelated to jdbc PreparedStatements) As of build 302, this method is equivalent to setPrepareThreshold(1).
    
    Specified by:
    
    setUseServerPrepare in interface PGStatement
    
    Parameters:
    
    flag - use server prepare
    
    Throws:

  - isUseServerPrepare
```
public boolean isUseServerPrepare()
```
    Description copied from interface: PGStatement
    
    Checks if this statement will be executed as a server-prepared statement. A return value of true indicates that the next execution of the statement will be done as a server-prepared statement, assuming the underlying protocol supports it.
    
    Specified by:
    
    isUseServerPrepare in interface PGStatement
    
    Returns:
    
    true if the next reuse of this statement will use a server-prepared statement
