pg_delete deletes records from a table
specified by the keys and values in conditions.
If flags is specified,
pg_convert is applied to
conditions with the specified flags.
By default pg_delete passes raw values.
Values must be escaped or the PGSQL_DML_ESCAPE flag
must be specified in flags.
PGSQL_DML_ESCAPE quotes and escapes parameters/identifiers.
Therefore, table/column names become case sensitive.
Note that neither escape nor prepared query can protect LIKE query,
JSON, Array, Regex, etc. These parameters should be handled
according to their contexts. i.e. Escape/validate values.

conditions
An array whose keys are field names in the table table_name,
and whose values are the values of those fields that are to be deleted.

Any number of PGSQL_CONV_FORCE_NULL,
PGSQL_DML_NO_CONV,
PGSQL_DML_ESCAPE,
PGSQL_DML_EXEC,
PGSQL_DML_ASYNC or
PGSQL_DML_STRING combined. If PGSQL_DML_STRING is part of the
flags then query string is returned. When PGSQL_DML_NO_CONV
or PGSQL_DML_ESCAPE is set, it does not call pg_convert internally.
