Passed to pg_fetch_array(). Return a numerically indexed array of field
numbers and values.

Passed to pg_fetch_array(). Return an array of field values
that is both numerically indexed (by field number) and associated (by field name).

was empty.
-
PGSQL_COMMAND_OK
(integer)
-
Returned by pg_result_status(). Successful completion of a
command returning no data.
-
PGSQL_TUPLES_OK
(integer)
-
Returned by pg_result_status(). Successful completion of a command
returning data (such as a SELECT or SHOW).

Returned by pg_result_status(). Copy Out (from server) data
transfer started.
-

Returned by pg_result_status(). A fatal error
occurred.
-
PGSQL_TRANSACTION_IDLE
(integer)
-
Returned by pg_transaction_status(). Connection is
currently idle, not in a transaction.
-
PGSQL_TRANSACTION_ACTIVE
(integer)
-
Returned by pg_transaction_status(). A command
is in progress on the connection. A query has been sent via the connection
and not yet completed.
-
PGSQL_TRANSACTION_INTRANS
(integer)
-
Returned by pg_transaction_status(). The connection
is idle, in a transaction block.
-
PGSQL_TRANSACTION_INERROR
(integer)
-
Returned by pg_transaction_status(). The connection
is idle, in a failed transaction block.
-
PGSQL_TRANSACTION_UNKNOWN
(integer)

-
Passed to pg_result_error_field().
The severity; the field contents are ERROR,

translation of one of these. Always present.
-
PGSQL_DIAG_SQLSTATE
(integer)
-
Passed to pg_result_error_field().
The SQLSTATE code for the error. The SQLSTATE code identifies the type of error
that has occurred; it can be used by front-end applications to perform specific
operations (such as error handling) in response to a particular database error.
This field is not localizable, and is always present.
-
PGSQL_DIAG_MESSAGE_PRIMARY

-
Passed to pg_result_error_field().
The primary human-readable error message (typically one line). Always present.
-
PGSQL_DIAG_MESSAGE_DETAIL

-
Passed to pg_result_error_field().
Detail: an optional secondary error message carrying more detail about the problem. May run to multiple lines.
-
PGSQL_DIAG_MESSAGE_HINT
(integer)
-
Passed to pg_result_error_field().

-
PGSQL_DIAG_STATEMENT_POSITION
(integer)
-
Passed to pg_result_error_field().
A string containing a decimal integer indicating an error cursor position as an index into the original

-
PGSQL_DIAG_INTERNAL_POSITION
(integer)
-
Passed to pg_result_error_field().
This is defined the same as the PG_DIAG_STATEMENT_POSITION field, but
it is used when the cursor position refers to an internally generated
command rather than the one submitted by the client. The
PG_DIAG_INTERNAL_QUERY field will always appear when this
field appears.
-
PGSQL_DIAG_INTERNAL_QUERY
(integer)
-
Passed to pg_result_error_field().
The text of a failed internally-generated command. This could be, for example, a
SQL query issued by a PL/pgSQL function.
-
PGSQL_DIAG_CONTEXT
(integer)
-
Passed to pg_result_error_field().
An indication of the context in which the error occurred. Presently
this includes a call stack traceback of active procedural language
functions and internally-generated queries. The trace is one entry

-
PGSQL_DIAG_SOURCE_FILE

-
Passed to pg_result_error_field().
The name of the PostgreSQL source-code function reporting the error.
-
PGSQL_ERRORS_TERSE

-
Passed to pg_set_error_verbosity().
Specified that returned messages include severity, primary text,
and position only; this will normally fit on a single line.
-

The default mode produces messages that include the above
plus any detail, hint, or context fields (these may span
multiple lines).

PGSQL_ERRORS_VERBOSE
(integer)
-
Passed to pg_set_error_verbosity().
The verbose mode includes all available fields.
-
PGSQL_STATUS_LONG
(integer)
-
Passed to pg_result_status(). Indicates that
numerical result code is desired.
