Structs

• PreparedStatement
  Client lifetime-bound prepared statement
• Spi
• SpiClient
• SpiCursor
  An SPI Cursor from a query
• SpiHeapTupleData
  Represents the set of pg_sys::Datums in a pg_sys::HeapTuple
• SpiHeapTupleDataEntry
  Represents a single pg_sys::Datum inside a SpiHeapTupleData
• SpiTupleTable
• UnknownVariant

Enums

• Error
  Set of possible errors pgx might return while working with Postgres SPI
• SpiErrorCodes
  These match the Postgres #defined constants prefixed SPI_ERROR_* that you can find in pg_sys. It is hypothetically possible for a Postgres-defined status code to be 0, AKA NULL, however, this should not usually occur in Rust code paths. If it does happen, please report such bugs to the pgx repo.
• SpiOkCodes
  These match the Postgres #defined constants prefixed SPI_OK_* that you can find in pg_sys.

Traits

• Query
  A generalized interface to what constitutes a query

Functions

• quote_identifier
  A safe wrapper around pg_sys::quote_identifier. Returns a properly quoted identifier. For instance for a column or table name such as "my-table-name"
• quote_literal
  A safe wrapper around pg_sys::quote_literal_cstr. Returns a properly quoted literal such as a TEXT literal like 'my string with spaces'.
• quote_qualified_identifier
  A safe wrapper around pg_sys::quote_qualified_identifier. Returns a properly quoted name of the following format qualifier.ident. A common usecase is to qualify a table_name for example "my schema"."my table"
