API

class alembic_pg_autogen.ops.CreateFunctionOp(desired: alembic_pg_autogen.inspect.FunctionInfo)

Bases: alembic.operations.ops.MigrateOperation

Create a new PostgreSQL function.

Initialization

desired: alembic_pg_autogen.inspect.FunctionInfo = None

reverse() → alembic_pg_autogen.ops.DropFunctionOp

Reverse is dropping the newly created function.

to_diff_tuple() → tuple[str, str, str, str]

Return a hashable tuple for debugging and comparison.

class alembic_pg_autogen.ops.ReplaceFunctionOp(current: alembic_pg_autogen.inspect.FunctionInfo, desired: alembic_pg_autogen.inspect.FunctionInfo)

Bases: alembic.operations.ops.MigrateOperation

Replace an existing PostgreSQL function with a new definition.

Initialization

current: alembic_pg_autogen.inspect.FunctionInfo = None

desired: alembic_pg_autogen.inspect.FunctionInfo = None

reverse() → alembic_pg_autogen.ops.ReplaceFunctionOp

Reverse is replacing with the old definition.

to_diff_tuple() → tuple[str, str, str, str]

Return a hashable tuple for debugging and comparison.

class alembic_pg_autogen.ops.DropFunctionOp(current: alembic_pg_autogen.inspect.FunctionInfo)

Bases: alembic.operations.ops.MigrateOperation
