The functions have been divided into three sections:
Connection, Result, Large Objects.
Connection, Result, Large Objects. For details please
read L<libpq>.
=head2 1. Connection
With these functions you can establish and close a connection to a
database. In Libpq a connection is represented by a structure called
PGconn. Using the appropriate methods you can access almost all
fields of this structure.
PGconn.
When opening a connection a given database name is always converted to
lower-case, unless it is surrounded by double quotes. All unspecified
parameters are replaced by environment variables or by hard coded defaults:
parameter environment variable hard coded default
--------------------------------------------------
host PGHOST localhost
port PGPORT 5432
options PGOPTIONS ""
tty PGTTY ""
dbname PGDATABASE current userid
user PGUSER current userid
password PGPASSWORD ""
Using appropriate methods you can access almost all fields of the
returned PGconn structure.
$conn = Pg::setdbLogin($pghost, $pgport, $pgoptions, $pgtty, $dbname, $login, $pwd)
Opens a new connection to the backend. The connection identifier $conn
( a pointer to the PGconn structure ) must be used in subsequent commands
for unique identification. Before using $conn you should call $conn->status
to ensure, that the connection was properly made.
$conn = Pg::setdb($pghost, $pgport, $pgoptions, $pgtty, $dbname)
Opens a new connection to the backend. You may use an empty string for
any argument, in which case first the environment is checked and then
hard-coded defaults are used. The connection identifier $conn ( a pointer
to the PGconn structure ) must be used in subsequent commands for unique
identification. Before using $conn you should call $conn->status to ensure,
that the connection was properly made. Use the methods below to access
the contents of the PGconn structure.
The method setdb should be used when username/password authentication is
not needed.
$conn = Pg::connectdb("option1=value option2=value ...")
Opens a new connection to the backend using connection information in a string.
Possible options are: dbname, host, user, password, authtype, port, tty, options.
The database-name will be converted to lower-case, unless it is surrounded by
double quotes. The connection identifier $conn (a pointer to the PGconn structure)
must be used in subsequent commands for unique identification. Before using $conn

to establish a new connection.
$ret = $conn->requestCancel
Abandon processing of the current query. Regardless of the return value of
requestCancel, the application must continue with the normal result-reading
sequence using getResult. If the current query is part of a transaction,
cancellation will abort the whole transaction.

$ret = $conn->getline($string, $length)
Reads a string up to $length - 1 characters from the backend.
getline returns EOF at EOF, 0 if the entire line has been read,
and 1 if the buffer is full. If a line consists of the two
characters "\." the backend has finished sending the results of

$conn->putline($string)
Sends a string to the backend. The application must explicitly
send the two characters "\." to indicate to the backend that
it has finished sending its data.
$ret = $conn->endcopy
This function waits until the backend has finished the copy.
It should either be issued when the last string has been sent
to the backend using putline or when the last string has
been received from the backend using getline. endcopy returns
0 on success, nonzero otherwise.

$ret = $conn->sendQuery($string, $query)
Submit a query to Postgres without waiting for the result(s). After
successfully calling PQsendQuery, call PQgetResult one or more times
to obtain the query results. PQsendQuery may not be called again until
getResult has returned NULL, indicating that the query is done.
$result = $conn->getResult
Wait for the next result from a prior PQsendQuery, and return it. NULL
is returned when the query is complete and there will be no more results.
getResult will block only if a query is active and the necessary response
data has not yet been read by PQconsumeInput.
$ret = $conn->isBusy
Returns TRUE if a query is busy, that is, PQgetResult would block waiting
for input. A FALSE return indicates that PQgetResult can be called with
assurance of not blocking.
$result = $conn->consumeInput
If input is available from the backend, consume it. After calling consumeInput,
the application may check isBusy and/or notifies to see if their state has changed.
$ret = $conn->getline($string, $length)
Reads a string up to $length - 1 characters from the backend.
getline returns EOF at EOF, 0 if the entire line has been read,
and 1 if the buffer is full. If a line consists of the two
characters "\." the backend has finished sending the results of
the copy command.
$ret = $conn->putline($string)
Sends a string to the backend. The application must explicitly
send the two characters "\." to indicate to the backend that
it has finished sending its data.
$ret = $conn->getlineAsync($buffer, $bufsize)
Non-blocking version of getline. It reads up to $bufsize
characters from the backend. getlineAsync returns -1 if
the end-of-copy-marker has been recognized, 0 if no data
is avilable, and >0 the number of bytes returned.
$ret = $conn->putnbytes($buffer, $nbytes)
Sends n bytes to the backend. Returns 0 if OK, EOF if not.
$ret = $conn->endcopy
This function waits until the backend has finished the copy.
It should either be issued when the last string has been sent
to the backend using putline or when the last string has
been received from the backend using getline. endcopy returns
