4.31 sequences

The view sequences contains all sequences defined in the current database. Only those sequences are shown that the current user has access to (by way of being the owner or having some privilege).

4-29: sequences Columns
Name Data Type Description
sequence_catalog sql_identifier Name of the database that contains the sequence (always the current database)
sequence_schema sql_identifier Name of the schema that contains the sequence
sequence_name sql_identifier Name of the sequence
data_type character_data The data type of the sequence. In PostgreSQL, this is currently always bigint.
numeric_precision cardinal_number This column contains the (declared or implicit) precision of the sequence data type (see above). The precision indicates the number of significant digits. It may be expressed in decimal (base 10) or binary (base 2) terms, as specified in the column numeric_precision_radix.
numeric_precision_radix cardinal_number This column indicates in which base the values in the columns numeric_precision and numeric_scale are expressed. The value is either 2 or 10.
numeric_scale cardinal_number This column contains the (declared or implicit) scale of the sequence data type (see above). The scale indicates the number of significant digits to the right of the decimal point. It may be expressed in decimal (base 10) or binary (base 2) terms, as specified in the column numeric_precision_radix.
